Exploring Biodiversity

What is biodiversity and why is it important?

• Biodiversity refers to the number of species in a single habitat.

• Biodiversity is only important for agricultural practices.

• Biodiversity is the study of animal behavior in captivity.

• Biodiversity is the variety of life on Earth, and it is important for ecosystem stability, resilience, and human well-being.

Name three levels of biodiversity.

• climate diversity

• genetic diversity, species diversity, ecosystem diversity

• habitat diversity

• population diversity

What are the main threats to biodiversity?

• Urban development

• Agricultural expansion

• Natural disasters

• Habitat loss, climate change, pollution, overexploitation, invasive species.

How does habitat destruction affect biodiversity?

• Habitat destruction increases biodiversity by creating new species.

• Habitat destruction only affects plant species, not animals.

• Habitat destruction has no impact on biodiversity.

• Habitat destruction reduces biodiversity by causing species loss and disrupting ecosystems.

Explain the concept of an ecosystem and its relation to biodiversity.

• An ecosystem is only made up of plants.

• An ecosystem is a static environment with no interactions between organisms.

• Biodiversity refers to the number of ecosystems in a region.

• An ecosystem is a community of organisms and their environment, and biodiversity is the variety of life within that ecosystem.

What role do keystone species play in an ecosystem?

• Keystone species play a critical role in maintaining the structure and balance of an ecosystem.

• Keystone species have no significant impact on ecosystem dynamics.

• Keystone species are only found in marine environments.

• Keystone species are the most abundant species in an ecosystem.

How can conservation efforts help protect biodiversity?

• Conservation efforts protect biodiversity by preserving habitats and species, promoting sustainable practices, and restoring ecosystems.

• Conservation efforts promote the extinction of invasive species.

• Conservation efforts focus solely on urban development.

• Conservation efforts increase pollution levels in ecosystems.

What is the significance of genetic diversity within a species?

• Genetic diversity is irrelevant to species survival.

• Genetic diversity leads to uniformity within a species.

• Genetic diversity only affects physical appearance.

• Genetic diversity is crucial for adaptation, resilience, and survival of a species.

Describe the impact of climate change on biodiversity.

• Climate change has no effect on biodiversity.

• Biodiversity increases due to climate change.

• Climate change only affects human populations, not biodiversity.

• Climate change negatively impacts biodiversity by causing habitat loss, altering ecosystems, and increasing extinction rates.

What are some examples of biodiversity hotspots around the world?

• Sahara Desert

• Great Barrier Reef

• Examples of biodiversity hotspots include the Amazon rainforest, the Himalayas, the Caribbean islands, the Western Ghats of India, and the Madagascar and Indian Ocean islands.

• Rocky Mountains
