2.13 Ecological Succession CFU

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 soil and some organisms still remain, such as after a forest fire.

Front

What role do lichens play in primary succession?

Back

Lichens help break down rock into soil through chemical weathering, allowing other plants to grow.

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

How does biodiversity change during ecological succession?

Back

Biodiversity typically increases during succession as more species of plants and animals establish themselves in the ecosystem.

Front

What is the difference between pioneer species and climax species?

Back

Pioneer species are the first organisms to colonize a barren environment, while climax species are those that dominate in a stable ecosystem.

Front

What factors can influence the rate of ecological succession?

Back

Factors include the type of disturbance, climate, soil quality, and the availability of species to colonize the area.

Front

What is the significance of soil in secondary succession?

Back

Soil provides nutrients and a medium for plants to grow, allowing for faster recovery and establishment of a new community after a disturbance.

Front

How do human activities impact ecological succession?

Back

Human activities, such as deforestation and urbanization, can disrupt natural succession processes and lead to loss of biodiversity.
