Biodiversity & Ecological Succession

Front

What is biodiversity?

Back

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

What are pioneer species?

Back

Pioneer species are the first organisms to colonize previously disrupted or damaged ecosystems, helping to create soil and establish a habitat for other species.

Front

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, involving a series of stages from pioneer species to a climax community.

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 diverse array of species.

Front

Why is biodiversity important?

Back

Biodiversity is crucial because all species depend on each other for survival; the extinction of one species can lead to the extinction of others that rely on it.

Front

Which biome is the most biodiverse?

Back

The rainforest is the most biodiverse biome, hosting a vast number of species compared to other biomes.

Front

What role do decomposers play in an ecosystem?

Back

Decomposers break down dead organic matter, returning nutrients to the soil and making them available for plants and other organisms.

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 left the soil intact, such as after a forest fire.

Front

How do invasive species affect biodiversity?

Back

Invasive species can disrupt local ecosystems, outcompete native species, and reduce biodiversity by altering habitats.
