The cycle that moves water through evaporation, condensation, and precipitation.

What is the water cycle?

200

The group of organisms that make their own food.

What are producers (autotrophs)?

200

A species with a disproportionately large effect on its ecosystem.

What is a keystone species?

200

A J-shaped growth curve represents this type of growth.
 

What is exponential?

200

Succession starting where soil already exists.
