Succession

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize a barren environment in primary succession, such as lichens and mosses.

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.

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.

Front

What is secondary succession?

Back

Secondary succession is the process of ecological change that occurs in an area where a disturbance has destroyed an existing community but left the soil intact.

Front

What role do lichens play in succession?

Back

Lichens are pioneer species that help break down rock into soil, facilitating the growth of other plants.

Front

What is carrying capacity?

Back

Carrying capacity is the maximum number of individuals of a species that an environment can support sustainably.

Front

What are examples of climax communities?

Back

Examples of climax communities include mature forests, coral reefs, and grasslands.

Front

What is an intermediate species?

Back

Intermediate species are those that appear in the middle stages of ecological succession, following pioneer species.

Front

How do disturbances affect ecological succession?

Back

Disturbances can reset succession, leading to secondary succession, which can change the composition and structure of the community.

Front

What is the difference between primary and secondary succession?

Back

Primary succession starts on bare rock without soil, while secondary succession occurs in areas where soil is present after a disturbance.
