Biodiversity

What are some threats to biodiversity?

• Habitat destruction, climate change, pollution, overfishing, and invasive species.

• Increased agricultural production and urban development.

• Natural disasters and seasonal changes.

• Technological advancements and urbanization.

What is biodiversity?

• Biodiversity refers to the number of different species in a given area.

• Biodiversity is the variety of life in a given area, including the number of different species.

• Biodiversity is the study of ecosystems and their interactions.

• Biodiversity refers to the genetic variation within a single species.

What is a keystone species?

• A species that is the most abundant in an ecosystem.

• A species that has a disproportionately large effect on its environment relative to its abundance.

• A species that is at the top of the food chain.

• A species that is only found in a specific habitat.

How does biodiversity contribute to ecosystem services?

• Biodiversity has no impact on ecosystem services.

• Biodiversity enhances ecosystem services such as pollination, nutrient cycling, and climate regulation.

• Biodiversity only affects the aesthetic value of ecosystems.

• Biodiversity decreases the resilience of ecosystems.

What is an ecosystem?

• An ecosystem is a community of living organisms interacting with their physical environment.

• An ecosystem is a type of plant that grows in water.

• An ecosystem is a collection of non-living things in a specific area.

• An ecosystem is a group of people living in a city.

What is the impact of climate change on biodiversity?

• Climate change has no effect on biodiversity.

• Climate change can alter habitats, shift species distributions, and increase extinction rates, negatively impacting biodiversity.

• Climate change only affects terrestrial species, not aquatic ones.

• Climate change improves biodiversity by creating new habitats.

What is the difference between species richness and species evenness?

• Species richness refers to the number of different species in an area, while species evenness measures how evenly individuals are distributed among those species.

• Species richness measures how evenly individuals are distributed among species, while species evenness refers to the number of different species in an area.

• Species richness is the total number of individuals in a community, while species evenness is the variety of habitats present.

• Species richness is concerned with the genetic diversity within a species, while species evenness looks at the age distribution of individuals.

What role do humans play in biodiversity loss?

• Humans contribute to biodiversity loss through activities like deforestation, urbanization, and pollution.

• Humans help to increase biodiversity by protecting natural habitats.

• Humans have no significant impact on biodiversity.

• Humans only contribute to biodiversity loss through climate change.

How can conservation efforts help protect biodiversity?

• By preserving habitats and restoring ecosystems

• By promoting urban development

• By increasing pollution levels

• By encouraging deforestation

What is the significance of genetic diversity in ecosystems?

• It decreases competition among species.

• It increases resilience to environmental changes and diseases, contributing to ecosystem health.

• It leads to a higher rate of extinction among species.

• It has no impact on ecosystem health.
