Ecological Succession

Front

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, involving a series of progressive changes in species composition and community structure.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize previously disrupted or damaged ecosystems, initiating the ecological succession process.

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, 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 glacial 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 role do disturbances play in ecological succession?

Back

Disturbances, such as fires, storms, or human activities, can reset succession, allowing new species to establish and change the community structure.

Front

What is the difference between primary and secondary succession?

Back

Primary succession starts on bare rock or lifeless surfaces, while secondary succession occurs in areas where a disturbance has cleared out existing vegetation but left the soil.

Front

What are some examples of pioneer species?

Back

Examples of pioneer species include lichens, mosses, and certain grasses that can grow in harsh conditions.

Front

How does biodiversity change during succession?

Back

Biodiversity typically increases during succession as more species establish and interact, leading to a more complex ecosystem.

Front

What is a seral stage?

Back

A seral stage is an intermediate stage in the process of ecological succession, where specific communities of plants and animals develop before reaching a climax community.
