Succession

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 or glacier retreat.

Front

What is secondary succession?

Back

Secondary succession is the process of ecological change that occurs in an area where soil is present but the ecosystem has been disturbed, such as after a forest fire.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize previously uninhabited or disturbed land, such as lichens and mosses.

Front

What role do lichens play in primary succession?

Back

Lichens help to break down rock and contribute to soil formation, making it possible for other plants to grow.

Front

What is a climax community?

Back

A climax community is a stable and mature ecological community that has reached a final stage of succession.

Front

What is the difference between primary and secondary succession?

Back

Primary succession occurs in lifeless areas without soil, while secondary succession occurs in areas where soil is already present after a disturbance.

Front

What is the order of plant growth after a volcanic eruption?

Back

Lichens → Grasses → Shrubs → Trees.

Front

What happens to an ecosystem after a forest fire?

Back

The ecosystem undergoes secondary succession, where it regrows and restores itself.

Front

What is the significance of soil in succession?

Back

Soil is crucial for plant growth; it provides nutrients and a medium for roots, which is essential for both primary and secondary succession.

Front

What are some examples of disturbances that can lead to secondary succession?

Back

Disturbances include forest fires, floods, hurricanes, and human activities like farming.
