Front

What is an algae bloom?

Back

A rapid increase in the population of algae, often recognized by a discoloration of water.

Front

What type of succession occurs after a disturbance that leaves the soil intact?

Back

Secondary succession.

Front

What role do herbivores play in an ecosystem?

Back

Herbivores consume plants, helping to control plant populations and providing food for predators.
