Ecological Succession

Front

What is ecological succession?

Back

The process by which ecosystems change and develop over time, involving a series of stages leading to a stable climax community.

Front

What are the two main types of ecological succession?

Back

Primary succession and secondary succession.

Front

What is primary succession?

Back

The type of succession that occurs in lifeless areas where soil has not yet formed, such as after a volcanic eruption.

Front

What is secondary succession?

Back

The type of succession that occurs in areas where a disturbance has destroyed an existing community but left the soil intact, such as after a wildfire.

Front

What is a climax community?

Back

A stable and mature ecological community that has reached the final stage of succession.

Front

What role do pioneer species play in succession?

Back

Pioneer species, like lichens and mosses, are the first organisms to colonize barren environments, initiating the process of succession.

Front

How does soil presence affect the rate of succession?

Back

Soil presence allows for faster succession, as seen in secondary succession, where plants can grow more quickly compared to primary succession.

Front

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

Back

Lichens → Grasses → Shrubs → Trees.

Front

How do wildfires benefit ecosystems?

Back

Wildfires can replenish nutrients in the soil, promote new growth, and maintain the health of certain ecosystems.

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.
