Very cold, Frozen, Has 2 months of growing season, mosquitoes
Fur Trees, Thin needles, Cone shaped, Minnesota
Temperate (all four seasons) Oregon, Washington, BC
Temperate Deciduous Forest
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.
- At our latitude in N hemisphere (between 30° and 60°), low elevation air comes from SW
- area downwind of mountains is more arid (dry) than one would otherwise expect.
- First Law of Thermodynamics
- 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.
Words From Our Students
"StudyBlue is great for studying. I love the study guides, flashcards, and quizzes. So extremely helpful for all of my classes!"
Alice, Arizona State University
"I'm a student using StudyBlue, and I can 100% say that it helps me so much. Study materials for almost every subject in school are available in StudyBlue. It is so helpful for my education!"
Tim, University of Florida
"StudyBlue provides way more features than other studying apps, and thus allows me to learn very quickly! I actually feel much more comfortable taking my exams after I study with this app. It's amazing!"
Jennifer, Rutgers University
"I love flashcards but carrying around physical flashcards is cumbersome and simply outdated. StudyBlue is exactly what I was looking for!"
