Answer 10

Fossil Fuel Combustion, Biomass Combustion, Respiration, and Decomposition.

Question 11

Photosynthesis

Answer 11

Carbon Dioxide + Water + Sunlight = Oxygen and Glucose

Question 12

Cellular Respiration

Answer 12

Oxygen + Glucose = Carbon Dioxide and Water

Greenhouse Gases are what? (4)

Answer 13

Carbon Dioxide, Carbon Monoxide, Methane, and Water Vapor.

Question 14

Why is atmospheric carbon dioxide fluctuating by season?

Answer 14

No leafs means no photosynthesis and we burn fossil fuel during winter.

Question 15

Greenhouse Effect

Answer 15

Certain gases trap heat an it won’t bounce back.

Question 16

Climate Change

Answer 16

Some places are warming up more than others.

Question 17

What are the 2 forms of the Nitrogen Cycle?

Answer 17

Nitrogen Oxide.

Question 18

What’s the atmospheric component of the Nitrogen Cycle?

Answer 18

N2 as a gas in the atmosphere, comprises 78%.

Question 19

How does nitrogen get into organisms, since we can’t use N2 directly from the air?

Answer 19

Bacteria or lightning converts into ammonia, then nitrates, then plants take over.

Question 20
