What is the cultural and aesthetic value of biodiversity?

• It provides food resources

• It enriches cultures and human experiences

What is the Shannon Diversity Index used for?

• Measuring the number of species in an ecosystem.

• Calculating the total number of individuals in an ecosystem.

• Measuring biodiversity using richness and evenness.

• Determining the diversity of habitats in an ecosystem.

How are endangered species different from threatened species?

• Endangered species are likely to become extinct in the near future.

• Endangered species are in immediate danger of extinction.

• Threatened species are already extinct.

• Threatened species are not at risk of extinction.

What is a mass extinction?

• Gradual loss of species over time.

• Rapid loss of a large percentage of species in a short time.

• Slow increase in species diversity.

• Natural background extinction rate.
