Succession & Biodiversity

Front

What is succession in ecology?

Back

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 are pioneer species?

Back

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

Front

What is primary succession?

Back

Primary succession occurs in lifeless areas where there is no soil, 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 role do invasive species play in ecosystems?

Back

Invasive species can disrupt local ecosystems by outcompeting native species for resources, often leading to a decrease in biodiversity.

Front

What is carrying capacity?

Back

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

Front

How does biodiversity affect ecosystem stability?

Back

Higher biodiversity generally leads to greater ecosystem stability, resilience, and productivity, as diverse species can fulfill various ecological roles.

Front

What is an ecosystem?

Back

An ecosystem is a community of living organisms interacting with their physical environment, including both biotic and abiotic components.

Front

What is the difference between logistical and exponential growth?

Back

Exponential growth occurs when resources are unlimited, leading to a rapid increase in population size, while logistical growth occurs when resources are limited, resulting in a population that stabilizes at carrying capacity.

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 balance of species.
