6EF Formative - symbiosis and primary/secondary succession

Front

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, involving a series of stages that lead to a stable community.

Front

What is primary succession?

Back

Primary succession occurs in lifeless areas where soil has not yet formed, such as after a volcanic eruption or glacier retreat.

Front

What is secondary succession?

Back

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

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize barren environments during 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 succession.

Front

What is the main difference between primary and secondary succession?

Back

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

Front

What is commensalism?

Back

Commensalism is a type of symbiotic relationship where one organism benefits while the other is neither helped nor harmed.

Front

What is mutualism?

Back

Mutualism is a symbiotic relationship where both organisms benefit from the interaction.

Front

What is parasitism?

Back

Parasitism is a relationship where one organism benefits at the expense of another, harming it in the process.

Front

Give an example of primary succession.

Back

An example of primary succession is lichens growing on rocks following a volcanic eruption.
