Succession

Front

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, involving a series of progressive changes in species composition and community structure.

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, leading to the establishment of a biological community.

Front

What is secondary succession?

Back

Secondary succession occurs in areas where a disturbance has destroyed an existing community but left the soil intact, such as after a forest fire or flood.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize previously uninhabited or disturbed environments, playing a crucial role in the process of succession.

Front

Give an example of primary succession.

Back

An example of primary succession is the colonization of bare rock after a volcanic eruption, where lichens and mosses are the first to grow.

Front

Give an example of secondary succession.

Back

An example of secondary succession is the regrowth of a forest after a wildfire, where the soil remains and seeds can germinate.

Front

What role do disturbances play in succession?

Back

Disturbances, such as fires, floods, or human activities, can reset ecological succession, allowing new communities to develop and existing ones to change.

Front

How does soil formation occur in primary succession?

Back

In primary succession, soil formation occurs as pioneer species break down rock and organic matter accumulates, creating a substrate for other plants.

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, characterized by a diverse array of species.

Front

What factors influence the rate of succession?

Back

Factors influencing the rate of succession include the type of disturbance, climate, soil quality, and the availability of species.
