Succession

Front

What is a climax community?

Back

A climax community is a stable and mature ecological community that has reached a state of equilibrium, where species composition remains relatively unchanged over time.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize previously disrupted or damaged ecosystems, often leading to ecological succession.

Front

Give an example of a 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 process of ecological change that occurs in an area where no soil exists, such as after a volcanic eruption or glacier retreat.

Front

What is secondary succession?

Back

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

Front

What role do lichens play in succession?

Back

Lichens are pioneer species that help break down rock into soil, facilitating the process of primary succession.

Front

What is the order of succession?

Back

The order of succession refers to the sequence of species replacement in an ecosystem over time, typically starting with pioneer species and leading to a climax community.

Front

How do natural disasters affect ecosystems?

Back

Natural disasters like floods and tornadoes can lead to secondary succession by disturbing existing ecosystems and allowing new species to establish.

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 community but left the soil intact.

Front

What is an example of a climax community?

Back

A mature forest can be considered an example of a climax community, as it has reached a stable state with a diverse range of species.
