Succession

Front

What is succession?

Back

Succession is the process by which ecosystems change and develop over time, leading to a more stable community.

Front

What are the two main types of succession?

Back

The two main types of succession are primary succession and secondary succession.

Front

What is primary succession?

Back

Primary succession occurs in lifeless areas where soil has not yet formed, such as after a volcanic eruption or glacier retreat.

Front

What is secondary succession?

Back

Secondary succession occurs in areas where a disturbance has destroyed an existing community but left the soil intact, such as after a forest fire.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize barren environments in primary succession, such as mosses and lichens.

Front

What role do pioneer species play in primary succession?

Back

Pioneer species help break down rock and rebuild soil, making it possible for other plants to grow.

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

How does secondary succession differ from primary succession?

Back

Secondary succession starts with soil already present, while primary succession begins in lifeless areas without soil.

Front

What are some examples of disturbances that can lead to secondary succession?

Back

Examples include forest fires, hurricanes, and human activities like farming.

Front

What is the significance of biodiversity in a successional community?

Back

Biodiversity increases the resilience of an ecosystem, allowing it to recover from disturbances more effectively.
