Biodiversity & Ecosystem Stability

What is biodiversity?

The variety of different species of living organisms on Earth or within an ecosystem.

Why is biodiversity important?

It helps maintain stable ecosystems and supports resources needed by humans.

How can high biodiversity contribute to ecosystem stability?

Multiple species can provide alternative feeding relationships and ecological functions.

Why can ecosystems with low biodiversity be vulnerable?

The loss of one species may have a greater effect on the remaining community.

What is species richness?

The number of different species present in an area.

What is habitat diversity?

The variety of different habitats within an area.

Why are tropical rainforests important for biodiversity?

They provide many habitats supporting large numbers of species.

Why are coral reefs important for biodiversity?

They support complex communities with many interacting species.

How can habitat destruction reduce biodiversity?

It removes food, shelter and breeding sites, causing population declines.

How can pollution reduce biodiversity?

It may kill organisms or make habitats unsuitable.

How can climate change reduce biodiversity?

Changing conditions may exceed the tolerance of some species.

How can invasive species reduce biodiversity?

They may outcompete, prey on or spread disease to native species.

Why is maintaining biodiversity important for agriculture?

Diverse ecosystems support pollination, soil fertility and natural pest control.

Why is maintaining biodiversity important for medicine?

Organisms may provide chemicals and genetic resources useful in developing medicines.

What is conservation?

The protection and management of species, habitats and ecosystems.

Why is conservation important?

It helps prevent extinctions and preserve biodiversity.

What is the difference between biodiversity and abundance?

Biodiversity describes variety of species, while abundance describes numbers of organisms.

Can a habitat contain many individuals but low biodiversity?

Yes, if most individuals belong to only a few species.
