Back

Biodiversity refers to the variety of living organisms in a particular ecosystem, including different species of plants, animals, and microorganisms.

Front

Why is biodiversity important in an ecosystem?

Back

Biodiversity is important because it allows ecosystems to withstand major changes and disturbances, ensuring stability and resilience.

Front

Which ecosystem has higher biodiversity: a rain forest or a desert?

Back

A rain forest has higher biodiversity compared to a desert.

Front

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, often following a disturbance.

Front

What is primary succession?

Back

Primary succession is the development of an ecosystem in an area where no soil exists, such as after a volcanic eruption.

Front

What is the first stage of primary succession?

Back

The first stage of primary succession is the colonization of bare rock by pioneer species like lichens.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize a barren environment, helping to create soil for other plants.

Front

What is a climax community?

Back

A climax community is a stable and mature ecosystem that has reached its greatest growing potential.

Front

What is secondary succession?

Back

Secondary succession is the process of recovery and re-establishment of an ecosystem after a disturbance that does not destroy the soil.

Front

What role do lichens play in ecological succession?

Back

Lichens help break down rocks and contribute to soil formation, making it possible for other plants to grow.
