How do animals get nitrogen?

• photosynthesis

• assimilation

• eating plants and animals

• lightning

What process recycles nitrogen to the atmosphere as nitrogen gas?

• assimulation

• denitrification

• ammonification

• nitrification

What is the first thing to come back after succession?

• pioneer species

• intermediate species

• climax species

• mature trees

What is the difference between primary and secondary succession?

• Primary only occurs in the dessert

• Secondary occurs with bare rock as the start.

• Secondary starts with soil instead of bare rock.

• Both occur from fire.

What might be one cause of secondary succession (where all plants and animals are gone, but soil remains)?

• Fire

• clearcutting forest

• Construction

• All could lead to succession
