Understanding Biodiversity Quiz

What are the three varieties of biodiversity mentioned in the video?

• Genetic diversity, species diversity, habitat diversity

• Genetic diversity, ecological diversity, cultural diversity

• Species diversity, habitat diversity, population diversity

• Genetic diversity, habitat diversity, agricultural diversity

Why is genetic diversity important for a species?

• It helps in increasing the population size.

• It allows for better adaptation to environmental changes.

• It reduces competition among species.

• It ensures all individuals are identical.

What is species richness?

• The total number of individuals in a community.

• The number of different species in an ecosystem.

• The number of ecosystems in a region.

• The diversity of genetic traits within a species.

Which of the following is NOT one of the environmental stressors mentioned?

• Climatic stressors

• Economic stressors

• Chemical stressors

• Biological stressors

What happens during a population bottleneck?

• A population increases in genetic diversity.

• Most of the population is killed off, reducing genetic diversity.

• New species are introduced to the ecosystem.

• Habitats are restored to their original state.

How do specialist species differ from generalist species?

• Specialist species can thrive in various environments.

• Specialist species require very specific resources.

• Generalist species are always endangered.

• Generalist species have very specific dietary needs.

What is the relationship between richness and evenness in measuring biodiversity?

• Richness refers to the number of individuals, while evenness refers to different species.

• Richness looks at the number of different species, while evenness assesses their relative abundance.

• Both richness and evenness refer to the same aspect of biodiversity.

• Richness is unrelated to biodiversity measurement.

Which community is considered more resilient to disturbances?

• A community with high richness and low evenness.

• A community with low richness and high evenness.

• A community with high richness and high evenness.

• A community with low species diversity.

What impacts do habitat loss have on biodiversity?

• It leads to an increase in generalist species.

• It causes a decrease in specialist species and impacts generalist species.

• It has no effect on biodiversity.

• It increases genetic diversity.

Why are pandas mentioned as an example of specialist species?

• They can survive in a wide range of habitats.

• They have very specific dietary and habitat requirements.

• They reproduce quickly and easily.

• They are not endangered.
