Ecological succession

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize an area and begin the process of ecological succession.

Front

Give examples of pioneer species in primary succession.

Back

Mosses and lichens are examples of pioneer species in primary succession.

Front

What is primary succession?

Back

Primary succession is the ecological process that occurs in an area that has no soil, such as after a volcanic eruption or glacier retreat.

Front

What is secondary succession?

Back

Secondary succession is the ecological process that occurs in an area that has soil and was previously inhabited, such as after a forest fire.

Front

What is the main difference between primary and secondary ecological succession?

Back

Primary succession begins without soil, while secondary succession begins with soil.

Front

What role do pioneer species play in ecological succession?

Back

Pioneer species help to create soil and conditions that allow other species to thrive.

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.

Front

What factors can influence the rate of ecological succession?

Back

Factors include climate, soil type, availability of species, and disturbances.

Front

What is a disturbance in the context of ecological succession?

Back

A disturbance is an event that disrupts the structure or function of an ecosystem, such as fire, flood, or human activity.

Front

How does soil formation occur during primary succession?

Back

Soil formation occurs as pioneer species break down rock and organic matter accumulates.
