Ecological Succession

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, involving a series of progressive changes in species composition and community structure.

Front

What are the two main types of ecological succession?

Back

The two main types of ecological succession are primary succession and secondary succession.

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 ecosystem 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 a barren environment in primary succession, often including lichens and mosses.

Front

What role do pioneer species play in succession?

Back

Pioneer species help to create soil and conditions that allow other species to establish, facilitating the process of succession.

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, characterized by a diverse array of species.

Front

How does a forest fire affect ecological succession?

Back

A forest fire can lead to secondary succession, where the ecosystem begins to regrow and recover after the disturbance.

Front

What is the enhanced greenhouse effect?

Back

The enhanced greenhouse effect refers to the increased warming of Earth's surface due to human activities that increase greenhouse gas concentrations.

Front

What is global warming?

Back

Global warming is the long-term rise in Earth's average surface temperature due to human activities, primarily the burning of fossil fuels.
