Question 6

What type of organisms perform the processes of photosynthesis and cellular respiration?

Answer 6

Question 7

How humans affect the carbon and nitrogen cycles.

Answer 7

By adding fertilizer to the soil.

Question 8

Differentiate between how energy and how carbon flow through a food chain.

Answer 8

The energy follows the 10% rule through the food chain. Carbon gets bonded to the energy during photosynthesis so the carbon also moves with the energy therefore following the 10% rule.

Question 9

How are all the cycles similar and different?

Answer 9

Similar: Plants and animals move through.
Carbon: Goes through photosynthesis.
Nitrogen: Needs bacteria to break down N2 to a compound formed.
Phosphorus: Starts in rocks.
