Ecological Succession

Front

What is ecological succession?

Back

The process of change in the species structure of an ecological community over time.

Front

What is primary succession?

Back

Ecological succession that occurs in an area where there was no previous community, such as bare rock or sand, beginning with pioneer organisms.

Front

What is secondary succession?

Back

Ecological succession that occurs in an area where a disturbance has destroyed an existing community but left the soil intact.

Front

What are pioneer species?

Back

Species that are the first to colonize previously disrupted or damaged ecosystems, such as lichens and mosses.

Front

Give an example of primary succession.

Back

A volcanic island forming new land where life begins with pioneer species like lichens.

Front

What is a climax community?

Back

A stable and mature ecological community that has reached a steady state through the process of succession.

Front

Which organisms are typically considered pioneer species?

Back

Lichens, mosses, and certain types of grasses.

Front

What role do lichens play in soil formation?

Back

Lichens contribute to soil formation by breaking down rock and contributing organic material as they die.

Front

What is the difference between primary and secondary succession?

Back

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

Front

What is the significance of soil in ecological succession?

Back

Soil provides nutrients and a habitat for organisms, facilitating the growth of plants and the development of ecosystems.
