What is a pioneer species?

Back

Pioneer species are the first organisms to colonize a barren environment in the initial stages of ecological succession.

What role do small shrubs and flowering plants play in succession?

Back

Small shrubs and flowering plants typically follow grasses in the process of ecological succession, contributing to the development of a more complex ecosystem.

Front

What is a climax community?

Back

A climax community is the final, stable stage of ecological succession, where the ecosystem reaches a state of equilibrium.
