Ecological Succession Review

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, leading to the gradual establishment of an ecosystem.

Front

What is a climax community?

Back

A climax community is a stable and mature ecological community that has reached the final stage of ecological succession, characterized by a diverse array of species.

Front

What is the correct order of ecological succession?

Back

The correct order of ecological succession is lichens - grasses - shrubs - trees.

Front

What is the first stage of primary succession?

Back

The first stage of primary succession is the colonization of bare rock by lichens and mosses.

Front

What is the final stage of ecological succession?

Back

The final stage of ecological succession is the climax community.

Front

What role do pioneer species play in succession?

Back

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

Front

Can climax communities vary in size?

Back

Yes, climax communities can vary in size and are not always large forests; they can be grasslands, deserts, or other ecosystems.

Front

What is secondary succession?

Back

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

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 a disturbance has destroyed an existing ecosystem but soil remains.

Front

What are some examples of pioneer species?

Back

Examples of pioneer species include lichens, mosses, and certain types of grasses.
