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 the two main types of ecological succession?

Back

The two main types of ecological 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 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 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 role do pioneer species play in succession?

Back

Pioneer species are the first organisms to colonize barren environments, helping to create soil and establish conditions for other species.

Front

Give an example of a pioneer species.

Back

Lichens and mosses are common examples of pioneer species that can grow on bare rock.

Front

What is the order of species appearance in primary succession?

Back

The order is: Rocks, Lichens & Mosses, Bushes & Shrubs, Trees.

Front

Why does primary succession take longer than secondary succession?

Back

Primary succession takes longer because it starts from bare rock and requires soil formation, while secondary succession begins with existing soil.

Front

What is a pioneer community?

Back

A pioneer community is the initial community of organisms that colonize a newly formed or disturbed area.
