Multiple Choice

What does it mean for nitrogen to be fixed.

1

Nitrogen is held firmly in place

2

Nitrogen is destroyed

3

Nitrogen is changed into a usable form

4

20

Multiple Choice

Why is the nitrogen cycle important for the survival of organisms in an ecosystem?

1

The nitrogen cycle recycles nitrogen through an ecosystem, making it available to all organisms.

2

The nitrogen cycle allows all organisms in an ecosystem to consume nitrogen instead of consuming each other.

3

The nitrogen cycle stores nitrogen in safe places, keeping it from entering an ecosystem.

4

The nitrogen cycle keeps organisms from consuming nitrogen in their ecosystem.
