A climax community is a stable and mature ecological community that has reached the final stage of succession.

Front

What is the difference between primary and secondary succession?

Back

Primary succession starts from bare rock or lifeless areas, while secondary succession starts from existing soil after a disturbance.

Front

Which type of succession is faster: primary or secondary?

Back

Secondary succession is faster than primary succession.

Front

What role do pioneer species play in succession?

Back

Pioneer species prepare the environment for other species by breaking down rock and creating soil.

Front

What is an example of a disturbance that can lead to secondary succession?

Back

A forest fire is an example of a disturbance that can lead to secondary succession.

Front

What is a disturbance in ecological terms?

Back

A disturbance is an event that significantly alters the structure of an ecosystem, affecting its composition and function.
