Ecological Succession

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 a barren environment in the initial stages of ecological succession, often helping to create conditions suitable for other species.

Front

What is a climax community?

Back

A climax community is a stable and mature ecological community that has reached its greatest growing potential, characterized by a diverse array of species.

Front

What is primary succession?

Back

Primary succession is the type of ecological succession that 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 is the type of ecological succession that 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 the difference between primary and secondary succession?

Back

Primary succession occurs in areas without soil, while secondary succession occurs in areas where soil is already present.

Front

What role do lichens play in primary succession?

Back

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

Front

What is the order of species in primary succession?

Back

The correct order in primary succession 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 the formation of soil, while secondary succession begins with existing soil.

Front

What are abiotic components in an ecosystem?

Back

Abiotic components are the non-living physical and chemical elements in an ecosystem, such as sunlight, water, air, and minerals.
