- B.
  
  A water body is damaged by excess nutrients like nitrogen.
- C.
  
  A piece of land is over fertilized.
Correct Answer
B. A water body is damaged by excess nutrients like nitrogen.
2.

The Greenhouse Effect is a problem that occurs when.
- A.
  
  A water body is destroyed by excess nutrients like nitrogen.
- B.
  
  Excess CO₂ causes too much heat to be trapped in the earth's atmosphere.
- C.
  
  A greenhouse plant receives too much fertilizer.
Correct Answer
B. Excess CO₂ causes too much heat to be trapped in the earth's atmosphere.
3.

Correct Answer
A. Condensation
8.

Which TWO cycles use bacteria and fungi, which are decomposers, that help the cycle?
- A.
  
  Water Cycle
- B.
  
  Carbon Cycle
- C.
  
  Nitrogen Cycle
Correct Answer(s)
B. Carbon Cycle
C. Nitrogen Cycle

Explanation
Bacteria break down dead organisms to return carbon back into the system. Bacteria break down animal waste to give usable nitrogen back to the system.
