Biodiversity refers to the wide variety of plants and animals in an ecosystem, contributing to its health and resilience.

Front

What does r-selected species mean?

Back

R-selected species are organisms that produce many offspring with little parental care, allowing for rapid population growth.

Front

What is ecological succession?

Back

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

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize previously uninhabited areas, playing a crucial role in primary succession.

Front

What is the difference between primary and secondary succession?

Back

Primary succession occurs in lifeless areas without soil, while secondary succession occurs in areas where a disturbance has destroyed an existing ecosystem but soil remains.

Front

What role do decomposers play in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the soil and supporting new plant growth.

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.
