Test 1 Summer

Illinois - Rockies, Dry, Grass, Trees don’t do well

Large temperate fluctuations, cold in winter, hot in summer, Occitillio- Drought deciduous drops leaves

Minimal Fluctuations, Winter dry season, Summer wet season, plant and insect diversity

• is generally warm at the equator and coolest at the poles.

• it’s warmer at the equator.
• Warm air rises, and thus it cools, so it loses water
• As air rises, it drops in temperature because it is colder at higher elevations.
• Cold air cannot hold as much water as warm air, so as the air rises, the water condenses and falls as rain.

• Some air goes N, some S.
• Air that has risen (and lost all its water) then descends at ~30° N and S.
• As it drops, the temperature rises, allowing it to hold more water, so it seldom rains.

• area downwind of mountains is more arid (dry) than one would otherwise expect.

• No energy transformation is 100% efficient, as energy is always lost as heat.
• Consider a cheetah that ingests 10,000 Calories of antelope in a week, and loses 3,000 from activities (hunting, mating, etc.) and energy left in its urine, feces, hair, nails, etc.
• If it gets larger by 500 Calories, where did the rest go?
• It’s lost as heat!

• (ex. Grass  antelope  lion)

• (more realistic/complex than food chain; energy arrows cross each other)

• (plants primarily: converting light energy to chemical energy)

• (returns elements bound in organisms to the soil, where they are recycled.
