Back

Secondary succession is the process of regrowth in an ecosystem after a disturbance, such as a forest fire, where soil and some organisms still exist.

Front

True, ecological succession generally leads to increased biodiversity over time.

Front

What is a climax community?

Back

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

Front

What role do abiotic factors play in succession?

Back

Abiotic factors, such as soil quality, climate, and water availability, influence the types of organisms that can thrive during succession.

Front

How does a forest fire lead to secondary succession?

Back

After a forest fire, the soil remains intact, allowing for rapid regrowth of plants and animals, which characterizes secondary succession.

Front

What is the difference between primary and secondary succession?

Back

Primary succession occurs in lifeless areas without soil, while secondary succession occurs in areas where a disturbance has destroyed an existing community but left the soil intact.
