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 stages that lead to a stable community.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize a barren environment, such as lichens and mosses, which help create soil.

Front

What is primary succession?

Back

Primary succession is the process of ecological change that occurs in an area where no soil exists, such as after a volcanic eruption.

Front

What is secondary succession?

Back

Secondary succession is the process of ecological change that occurs in an area where a disturbance has destroyed an existing ecosystem but left the soil intact.

Front

What role do pioneer species play in primary succession?

Back

Pioneer species create soil and add nutrients to the environment, allowing other plants to grow.

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.

Front

What is the difference between primary and secondary succession?

Back

Primary succession starts on bare rock without soil, while secondary succession occurs in areas where soil is already present after a disturbance.

Front

What are lichens?

Back

Lichens are symbiotic organisms made up of fungi and algae, often found as pioneer species in primary succession.

Front

What is the significance of soil formation in succession?

Back

Soil formation is crucial as it provides the necessary nutrients and habitat for plants and other organisms to thrive.

Front

What is an example of a disturbance that can lead to secondary succession?

Back

Examples of disturbances include forest fires, floods, or human activities like farming.
