Ecological Changes: Succession

Front

What is ecological succession?

Back

Ecological 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 a barren or disturbed area, initiating the process of ecological 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 glacier retreat.

Front

What is secondary succession?

Back

Secondary succession occurs in areas where a disturbance has destroyed an existing ecosystem but soil and some organisms still remain, 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 equilibrium, where species composition remains relatively unchanged.

Front

How does moving water contribute to weathering and erosion?

Back

Moving water erodes rocks and soil, transporting sediments and shaping landscapes over time.

Front

What role do plants play in soil development during succession?

Back

Plants contribute to soil development by adding organic matter through decomposition, which enriches the soil and supports further plant growth.

Front

What is the significance of biodiversity in a climax community?

Back

Biodiversity in a climax community enhances ecosystem stability, resilience, and productivity, allowing it to withstand environmental changes.

Front

How can a forest fire lead to secondary succession?

Back

A forest fire can clear out existing vegetation, allowing new plants to grow and initiate secondary succession, as the soil and some organisms remain.

Front

What is the difference between primary and secondary succession?

Back

Primary succession starts from bare rock or lifeless areas, while secondary succession occurs in areas where an ecosystem has been disturbed but soil and organisms still exist.
