Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the number of different species, genetic diversity, and the variety of ecosystems.

What is ecological succession?

Back

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

Front

What are pioneer species?

Back

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

Front

What is primary succession?

Back

Primary succession occurs in lifeless areas where there is no soil, such as after a volcanic eruption.

Front

What is secondary succession?

Back

Secondary succession occurs in areas where a disturbance has destroyed an existing ecosystem but soil and some organisms still remain.

Front

What role do lichens play in succession?

Back

Lichens are often the first organisms to grow in primary succession, helping to break down rocks and create soil.

Front

Why is biodiversity important for ecosystems?

Back

Biodiversity is important because it allows ecosystems to be more resilient to changes and disturbances, supporting a wider range of species.

Front

What is the difference between primary and secondary succession?

Back

Primary succession starts with bare rock and no soil, while secondary succession begins in areas where soil is already present.

Front

What factors can affect rabbit populations in an ecosystem?

Back

Factors include the availability of food, water, shelter, and the presence of predators.

Front

How do shrubs contribute to ecological succession?

Back

Shrubs provide habitat and food for various animals, and they help improve soil quality, paving the way for larger plants.
