  1. Weather is the condition of the temper in terms of temperature, wind, and atmospheric pressure. Climate is the types of weather patterns that a identify has, on average, over a long period of time. Weather is measured over a shorter period of time.
  2. Answers volition vary. Listing could include: deciduous trees, grasses, treefrogs, toads, flowering plants, and earthworms.
  3. Humidity is an important gene in defining a biome because as humidity increases, more often than not, and then does the diversity of plants and animals.
  4. Every bit you move from the equator to the poles, the intensity of solar radiation decreases. Equally a result, the average yearly temperature decreases as well from the equator to the poles.
  5. Answers are:
    1. This Chill hare has white fur and pocket-sized ears.
    2. The Chill hare looks smaller and has more than fur, smaller ears, and white fur.
  6. The ecological role of these grasses should exist like because each ecosystem of a particular biome type has organisms that play similar roles.
  7. If the sapsuckers didn't come to Texas for a year, other bird species who depend on the holes they drill would exist afflicted. This could lower the biodiversity of bird species in the forests.

Solve It p. 174

  1. Minneapolis is the furthest from a major body of h2o.
  2. Considering they are both at the same breadth.

Reading 7.2

  1. There are several ways deserts can form. They can class in areas of loftier atmospheric pressure where the condensation rate is lower than the evaporation charge per unit and therefore, very picayune precipitation falls. They tin can be acquired by the "rainshadow outcome" in mountainous regions. They can also exist known every bit fog deserts when the desert is formed from fog rolling in from common cold ocean h2o, causing a minor amount of precipitation.
  2. The phenomenon is called the "rainshadow result." Prevailing westerly winds blow moisture-filled air from the sea over the coast and up the western slope of a mountain range. The air cools and condenses, precipitating onto the western side of the mountain. As the air mass continues to motion over the mountain, its moisture content drops and the eastern side of the mountain is left with footling rainfall.
  3. The two types of grasslands are (1) savanna—characterized by a rainy and dry season, fires in savannas (after the dry season), and poor soil conditions prevent the growth of most trees, found in parts of the torrid zone; (two) temperate grassland—found in heart breadth regions, almost in interior of continents, rich in soil nutrients, trees uncommon.
  4. Graph C—averages about 190 mm (nineteen cm) of precipitation per year, which falls into the definition of a desert.
  5. Few trees alive on savannas considering of the poor soil conditions and fires. Some copse survive by growing in the soil of termite mounds. Termite activity adds nutrients to the soil that enable copse to take root and grow.
  6. A desert
  7. Answers will vary. Desert: cactus and sagebrush (producers), desert hare, rattle snake (consumers), bacteria (decomposers). Grassland: grasses, clover (producers), field mice, fox (consumers), fungi (decomposers).

Reading 7.iii

  1. a. Deciduous means that a tree loses its leaves at the end of a growing season. b. These copse are well suited for a biome with seasons because they are constitute in the center latitudes where the temperature and sunlight intensity changes are non equally extreme as in the poles merely have a wider range than the equatorial regions. This allows for a longer growing season than the pole areas simply less than the equatorial regions.
  2. Pair A represents the deciduous wood because at that place is ample precipitation throughout the year, and the temperatures are seasonal. Pair B represents the desert considering the temperatures are relatively stable and there is little to no atmospheric precipitation for much of the year with a wet season.
  3. Sustainability refers to an ecosystem's ability to maintain biodiversity. One reason biodiversity is important is that each organism in an ecosystem is a potential food source for some other organism. All species in an ecosystem play an important role. If biodiversity is present, the ecosystem is more sustainable because there are plenty of different species to act equally nutrient sources for other species.
  4. Tropical rainforests proceed our planet cooler when the leaves of the trees reflect green low-cal, which is not readily absorbed past greenhouse gases.
  5. Many foods we eat originate in tropical rainforests.
  6. The average temperature in the taiga is below freezing for at least six months of the twelvemonth.
  7. Evergreen trees have shallow roots to absorb surface h2o and melting snowfall. The needle shape of the leaves helps foreclose moisture loss.
  8. The air spaces between snow crystals prevent the ground underneath from losing more and more estrus equally the wintertime progresses.
  9. Arctic tundra plants would have shallow roots, be short, and accept minor surface areas to decrease loss of heat.
  10. The Arctic fob is brown in the summer and white in the winter (when snow is on the footing) for purposes of camouflage. It too appears to have more fur in the wintertime to aid go on it warm.
  11. Answers are:
    1. Permafrost is considered a carbon sink because it decreases the decomposition rate of dead plants, which, if immune to disuse, would release carbon dioxide into the atmosphere.
    2. Global warming would begin to cook permafrost, assuasive plants to decompose and release carbon dioxide into the atmosphere. Carbon dioxide is a greenhouse gas.

Connectedness

  1. A fire policy that requires all fires to be stopped and prevented does not rid the forest floor of hazardous fuel. Pine needles, cones, twigs, branches, plants, and small trees litter the wood floor, providing fuel to a burn down when it occurs. By eliminating even natural, low-intensity fires, humans accept affected the size and scale of future wildfires. The damage is more all-encompassing and the fires more than extreme.
  2. How fire is beneficial to a forest:
  • Clears the woods floor of any debris, including pine needles, cones, plants, and small trees.
  • Eliminates dangerous fuel that can make future fires even more widespread and dangerous.
  • Prevents fires from climbing minor trees to the upper, foliage levels of large copse. Once a burn reaches the upper levels, the burn worsens.
  • Enriches the soil with many nutrients to back up new found and tree growth. With new growth, animals take admission to plants and berries for food.
  • Kills diseases that may be nowadays in plants and copse.
  • Helps many fire-adjusted and burn-resistant copse to regenerate. Some have cones that are sealed tight with resin. Burn melts the resin, releases seeds in the cones, and new growth begins.
  1. Several burn-resistant or burn-adapted copse.
  • Lodge pole pines are non resistant to fire, but burn down opens their resin-sealed cones to release seeds into the soil. Lodge poles demand heat to regenerate.
  • Ponderosa pines and Douglas fir trees accept thick bark that can withstand low-intensity fires. They are non damaged during these types of fires.
  • Aspen trees have thin bark, but their hush-hush root system is insulated from the rut of fire. After a burn, roots transport up shoots, enabling the aspens to regenerate.
  • Sequoias are protected past bark that is two–iv feet thick. The bark acts as an insulator to protect the giant trees from estrus and fire damage. Sequoia seeds need the rich soil available after a fire to grow. Fires also thin out the forest and eliminate any competition the Sequoias seedlings may have for sunlight.

Action

Sample reflection: Since we were in the desert, we idea the dark would not get that common cold and our sleeping numberless would be adequate. We were cold, just in that location was no wood to exist found to make a fire then we could stay warm. We could have used warmer wearing apparel. Our compass did non turn out to exist quite as useful equally we expected. Since there were never any clouds blocking our view of the Dominicus or stars, nosotros could make out our management of travel pretty easily.

  1. Tropical rainforests proceed our planet libation when the leaves of the trees reflect greenish light, which is non readily absorbed by greenhouse gases.
  2. Many foods we consume originate in tropical rainforests.

Concepts

Reading 7.1

  1. d
  2. Humidity helps determine variety. In general, as humidity increases, diversity increases. Humidity and diversity tend to increase toward the equator, which accounts for the affect of breadth in defining a biome. Too, at the equator, the sunlight is direct and intense.
  3. The straight rays of the Lord's day never reach further north or southward than 23.5° (Tropics of Cancer and Capricorn). So, depending on where you are located, yous may demand to move southward or north to get within that belt of most intense and direct sunlight.
  4. The atmospheric condition would be milder due to the proximity to the water, which has a loftier specific heat. The h2o takes longer to heat up, but when information technology does, it stays warmer for longer, which moderates the temperature of the coastline.
  5. Ecosystems that are located on different continents can still have organisms that play similar roles—for case, those of predators, herbivores, and decomposers. For example, in any environment there will always be decomposers and a need for decomposers. Where plants grow, producers will gather to consume the plants.

Reading vii.2

  1. Ecosystems that are located on dissimilar continents can still have organisms that play similar roles—for example, those of predators, herbivores, and decomposers. For example, in any environs in that location will e'er exist decomposers and a need for decomposers. Where plants grow, producers will gather to consume the plants.
  2. Yakima, Washington is a rainshadow desert.
  3. A temperate grassland is like a savanna because trees are uncommon in both places. They are different in location: Savannas are in parts of the tropics, while temperate grasslands are in the centre latitude regions. They also are different in soil status: Savannas are poor, while grasslands are rich.
  4. Termites create mounds which can exist the growing area for some trees on the savanna.
  5. c

Reading vii.3

  1. Temperate deciduous forests have four seasons.
  2. Each afternoon, you would expect a thunderstorm because equally the warm, moist air in this surface area rises, information technology condenses and cools, forming clouds and pelting.
  3. The temperature of a tropical rainforest doesn't change very much because information technology is located near the equator.
  4. Then much area of the tropical rainforests is destroyed each twelvemonth to clear country to raise crops, graze animals, and use for lumber and firewood.
  5. Temperate rainforests are establish in the eye-latitude regions.
  6. A deciduous tree of a temperate deciduous forest is broad-leafed and loses leaves at the end of the growing flavor. An evergreen tree in a taiga is cone-shaped so that it can shed snowfall, has leaves that are needle-shaped to help prevent moisture loss, and roots that are shallow and widespread for water absorption. Also, they don't lose their needles, so they tin can photosynthesize every bit early as possible.
  7. An evergreen tree in a taiga is cone-shaped so it tin shed snow, has leaves that are needle-shaped to help prevent wet loss, and roots that are shallow and widespread for water assimilation. Also, they don't lose their needles, then they can photosynthesize as early as possible.
  8. Snow keeps the ground warm because it has insulation properties. The air pockets in the snow help contain the heat from the ground.
  9. Permafrost
  10. b
  11. The alpine tundra is in the middle latitude at loftier latitudes. Information technology is cold and windy, and the soil is sparse. In the Arctic tundra, at that place is permafrost with a thin layer of soil above.
  12. The difference in the length of days during the summer compared to the winter is due to the tilt of Earth on its axis. Even in the summer, the Sun is relatively depression on the horizon compared to the residual of the world. Since the chill areas are near or at the poles, the curvature of World makes the Lord's day appear low in the sky. The tilt of the axis makes the Sun appear to fix for only a few hours, if at all, which all simply eliminates its presence in the wintertime, making for long, cold, dark stretches.

Reading 7.2

  1. Sample answers for the American prairie:
    1. Grass is the main type of vegetation.
    2. Antelope, annoy, bison, black-footed ferret, blackness-tailed prairie dog, bull snake, coyote, fox, jackrabbit, mole, mouse, mount panthera leo, pronghorn sheep, red-tailed militarist, shrew, skunk.
    3. Since there is little if any shelter, many animals take adapted to burrowing to make their own shelter.

Reading 7.3

  1. a. They accept livelihoods and families they demand to support. b. Cutting down rainforests increases soil erosion, decreases agricultural possibilities, increases radiation emitted from the ground, and increases greenhouse gases (due to decrease in photosynthesizing leaves).
  2. In tropical rainforests, the leaves of trees reflect green visible lite, which is not readily captivated past greenhouse gases. Then trees in rainforests aid keep Globe cooler. Their metabolic processes too help to convert carbon dioxide into oxygen. Burning vegetation also takes carbon out of the biome and puts it into the atmosphere, farther increasing greenhouse gases and global warming.
  3. Answers are:
    1. tundra
    2. tropical rainforest
    3. tundra
    4. Graph:
      5. Average Temperature Graph
  4. Antarctica is very cold, and the precipitation that falls there is near always in the form of snow, usually only five cm per yr. The average temperature is –49 °C, making it the coldest place on Earth and domicile to 70% of Earth'due south fresh h2o in the form of water ice. The coldest temperature on record was recorded here: –88 °C! Animals that inhabit Antarctica have adapted to the cold past having insulating layers of fat or blubber to keep them warm. The Adelie penguin, Emperor penguin, Wendell seal, Antarctic skua, and Antarctic icefish all live in the Antarctic biome.

Sample answers for the Arctic tundra:

  1. They alive mainly on walrus, whale, caribou, seal, and fish. They build low-to-the-ground shelters that house several people in close quarters to conserve heat. In the warmer months, shelters are tents made of bone and animal skin. They can utilize ice and snow equally building materials in the winter, as they actually provide proficient insulation.
  2. They alive mainly on walrus, whale, caribou, seal, and fish. They hunt on the water on small one-person boats and as well punch holes in the body of water ice and expect in ambush for animals to come up up for air.
  3. They build low-to-the-ground shelters that house several people in shut quarters to conserve heat. They tin can use water ice and snow as building materials in the wintertime, equally they actually provide good insulation. In the warmer months, shelters are tents made of bones and animal skins.
  4. They wait into the Aurora Borealis and see images of their ancestors, friends, and family dancing in the sky in the next life.
