Chapter 57 and 58

Question 1

less energy

Answer 1

1. doesn’t, cause all of it
2. doesn’t all get digested
3. metabolic waste

Question 2

geochemical cycle

Answer 2

movement from and non-living reservoir into biotic community and back, exchange pool- section of reservoir that is available to biotic community, where life is

Question 3

nitrogen cycle

Answer 3

atmospheric N2 is not accessible for life like plants so nitrogen fixation (gas to solid) occurs to going into the ground and nitrogen fixing bacteria makes NH3 (amonia) and then into nitrifying bacteria and then into No3 that can be absorbed by plants and then dentrification (puts nitrogen back into the atmosphere) happen

Question 4

carbon reservoirs

Answer 4

soil, rock, fossil fuels, shallow ocean, deep ocean, atmosphere

Question 5

how does carbon enter and exit the biological community

Answer 5

exchange pool- photosynthesis
reservoir- atmospheric CO2, cellular respiration

Question 6

why is Greenhouse effect important for life

Answer 6

warms environment and is the exchange pool for life

Question 7

3 greenhouse gases

Answer 7

1. CO2
2. CH4
3. N2O

Question 8

What happens when the greenhouse effect is amplified

Answer 8

ozone layer is going down

Question 9

what is the importance of the ozone layer to the greenhouse effect

Answer 9

ozone creates cooling

Question 10

milanovitch cycles

Answer 10

every year the sun doesn’t go around the sun the same so some ages are closer to the sun so that could explain CO2 levels and temp.
