Ecological Succession

Front

What is ecological succession?

Back

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

Front

What are the two main types of ecological succession?

Back

Primary succession and secondary succession.

Front

What is primary succession?

Back

The development of an ecosystem in an area that was previously lifeless, such as after a volcanic eruption or glacier retreat.

Front

What is secondary succession?

Back

The recovery of an ecosystem after a disturbance that does not destroy the soil, such as after a forest fire or flood.

Front

What is a pioneer species?

Back

The first species to colonize a barren environment in primary succession, often lichens or mosses.

Front

What role do lichens play in primary succession?

Back

Lichens help break down rock into soil, making it possible for other plants to grow.

Front

What is a climax community?

Back

A stable and mature ecosystem that has reached the final stage of succession.

Front

How does biodiversity change during succession?

Back

Biodiversity typically increases during succession as more species establish and interact within the ecosystem.

Front

What is the difference between primary and secondary succession?

Back

Primary succession starts on bare rock or lifeless areas, while secondary succession occurs in areas where an ecosystem has been disturbed but soil remains.

Front

What factors can influence the rate of succession?

Back

Factors include climate, soil type, availability of species, and the nature of the disturbance.
