science 3q part 2

What does species richness refer to?

• The number of ecosystems in an area

• The number of different species in a specific area

• The genetic variation within a species

• The diversity of genes in an ecosystem

What is biodiversity?

• The number of species in a specific area

• The variety of life, including species, genes, and ecosystems

• The number of plants in an ecosystem

• The interaction between predators and prey

Which of the following best describes genetic diversity?

• The diversity of species in an ecosystem

• The diversity of genes within a species

• The variety of habitats in a given area

• The number of different species in an ecosystem

What is species diversity?

• The number of different habitats in an area

• The number of genes in a population

• The diversity among species in an ecosystem

• The conservation of species outside their natural habitats

What is ecosystem diversity?

• The diversity of genes within a species

• The number of species in an ecosystem

• The diversity of habitats in a given unit area

• The conservation of species in their natural habitat

Why is biodiversity important?

• It contributes to the beauty of nature only

• It ensures ecosystems remain healthy and supports human life

• It prevents species from evolving

• It only benefits animals

When is a species considered endangered?

• When it no longer exists anywhere on Earth

• When it is at very high risk of extinction in the wild

• When it is not at risk but has a low population

• When it is only found in zoos

What does it mean if a species is extinct?

• It is no longer found in the wild but exists in captivity

• It is likely to become endangered soon

• It no longer exists anywhere on Earth

• It has a stable population

What are threatened species?

• Species that are already extinct

• Species that will never be at risk of extinction

• Species that are likely to become endangered if conservation efforts are not made

• Species that are only found in zoos

What is wildlife conservation?

• The study of different animal species

• The efforts made to protect animal species and their habitats

• The domestication of wild animals

• The introduction of non-native species into new environments
