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.

Front

Why do populations of invasive species grow so quickly?

Back

They have no predators.

Front

What is genetic diversity?

Back

Genetic diversity is the variation of genes within a species or population in a given area.

Front

What is species diversity?

Back

Species diversity refers to the variety of different species within a given area, including the number of species and their relative abundance.

Front

What is an example of low species diversity?

Back

A marsh ecosystem is covered by a single species of cattail bulrushes.

Front

What is an invasive species?

Back

An invasive species is a non-native species that spreads widely in a new habitat and causes harm to the environment, economy, or human health.

Front

What is ecosystem diversity?

Back

Ecosystem diversity refers to the variety of ecosystems within a given area, including different habitats, communities, and ecological processes.

Front

What impact do invasive species have on biodiversity?

Back

Invasive species can reduce biodiversity by outcompeting native species for resources, disrupting food webs, and altering habitats.

Front

What is the significance of maintaining biodiversity?

Back

Maintaining biodiversity is crucial for ecosystem stability, resilience, and the provision of ecosystem services such as clean air, water, and pollination.

Front

What is the role of predators in an ecosystem?

Back

Predators help control the population of prey species, which can prevent overpopulation and maintain balance in the ecosystem.
