Ecological Succession

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 are the two main types of ecological succession?

Back

The two main types of ecological succession are primary succession and secondary succession.

Front

What is primary succession?

Back

Primary succession occurs in an area where no soil exists, such as after a volcanic eruption or glacial retreat.

Front

What is secondary succession?

Back

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

Front

How do lichens contribute to primary succession?

Back

Lichens contribute to primary succession by breaking down rock to form soil, which allows other plants to grow.

What is a pioneer species?

Back

A pioneer species is the first species to colonize a barren environment in the process of primary succession.

Front

Give an example of a pioneer species.

Back

Lichens and mosses are common examples of pioneer species.

Front

What role do disturbances play in ecological succession?

Back

Disturbances can reset ecological succession by creating opportunities for new species to colonize an area, leading to secondary succession.

Front

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

Back

An example of a disturbance that could lead to secondary succession is human activities such as deforestation.

Front

How does soil quality affect succession?

Back

Soil quality affects succession by determining which species can establish and thrive in an area, influencing the rate and direction of succession.
