Succession

Front

What is succession in ecology?

Back

Succession is the process by which ecosystems change and develop over time, involving a series of stages that lead to a stable community.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize previously disrupted or damaged ecosystems, often starting the process of succession.

What is a climax community?

Back

A climax community is a stable and mature ecological community that has reached the final stage of succession, characterized by a diverse array of species.

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.

How does biodiversity affect ecosystem resilience?

Back

Ecosystems with high biodiversity are more resilient and resistant to disturbances, making them better able to recover from catastrophes.

Front

What role do lichens play in succession?

Back

Lichens are often the first organisms to grow on bare rock in primary succession, helping to break down the rock and create soil.

Front

What is the order of plant growth in primary succession?

Back

The order is typically: Lichens → Grasses → Shrubs → Trees.

Front

What is an example of a climax community?

Back

A mature forest is an example of a climax community, where the ecosystem has reached stability.

Front

What is the difference between primary and secondary succession?

Back

Primary succession begins without soil and only bare rock, while secondary succession begins with soil already formed.
