Biodiversity and Succession Test

Front

What is an invasive species?

Back

An invasive species is a non-native organism that, when introduced to a new environment, disrupts the local ecosystem by outcompeting native species for resources.

Front

What is a biodiversity hotspot?

Back

A biodiversity hotspot is a biogeographic region that is both a significant reservoir of biodiversity and is threatened by human activities.

Front

What is the role of keystone species in an ecosystem?

Back

Keystone species are organisms that have a disproportionately large effect on their environment relative to their abundance, helping to maintain the structure of the ecosystem.

Front

What is ecological succession?

Back

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

Front

What is the significance of preserving entire ecosystems?

Back

Preserving entire ecosystems helps to maintain biodiversity and can save many unknown species from extinction.

Front

How does a reduction in a predator population affect biodiversity?

Back

A reduction in a predator population can lead to an increase in prey species, which may decrease overall biodiversity by overgrazing or overconsuming vegetation.

Front

What are lichens and where do they typically grow?

Back

Lichens are symbiotic organisms made up of fungi and algae, often found in harsh environments such as after a volcanic eruption.

Front

What is an endemic species?

Back

An endemic species is a species that is native to and restricted to a specific geographic area.

Front

What is the impact of deforestation on biodiversity?

Back

Deforestation leads to habitat loss, which can result in decreased biodiversity and the extinction of species.

Front

What is the relationship between biodiversity and ecosystem stability?

Back

Higher biodiversity generally leads to greater ecosystem stability, as diverse ecosystems are more resilient to changes and disturbances.
