Maintaining and benefits of Biodiversity

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 the risk of extinction for many species, threatening overall biodiversity.

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

• Climate change improves biodiversity by creating new habitats.

What is biodiversity?

• The total number of species in a specific area.

• The variety of life in a particular habitat or ecosystem, including the diversity of species, genetic variation, and ecosystem diversity.

• The study of how species interact with each other.

• The process of evolution in different species.

What is the relationship between biodiversity and ecosystem services?

• Higher biodiversity typically enhances ecosystem services, as diverse ecosystems are more productive and resilient, providing more benefits to humans.

• Biodiversity has no significant impact on ecosystem services.

• Lower biodiversity leads to more efficient ecosystem services.

• Ecosystem services are independent of biodiversity levels.

Why is biodiversity important for ecosystems?

• It increases the risk of extinction for species.

• It enhances ecosystem stability, resilience, and productivity.

• It reduces the availability of essential services like pollination.

• It leads to a decrease in nutrient cycling and water purification.

How do human activities impact biodiversity?

• Human activities lead to habitat destruction and species extinction.

• Human activities have no effect on biodiversity.

• Human activities only affect land animals, not aquatic life.

• Human activities improve biodiversity by creating new habitats.

What is the significance of genetic diversity?

• It decreases the chances of survival in changing environments.

• It is important for the adaptability of species to changing environments, as it increases the chances of survival and resilience against diseases.

• It has no impact on species' survival.

• It only affects the physical traits of organisms.

What is an example of a provisioning service?

• The supply of food, such as fruits, vegetables, and fish, that ecosystems provide to humans.

• The regulation of climate and air quality by forests and oceans.

• The cultural benefits provided by natural landscapes and biodiversity.

• The support of nutrient cycling and soil formation by microorganisms.

How can conservation efforts help maintain biodiversity?

• By creating more urban areas for development.

• By preserving species, restoring ecosystems, and maintaining ecological balance.

• By increasing pollution levels in natural habitats.

• By promoting the extinction of invasive species.

What are ecosystem services?

• Benefits that humans receive from ecosystems, including provisioning, regulating, cultural, and supporting services.

• Only the food and water provided by ecosystems.

• The negative impacts of ecosystems on human health.

• The services provided by urban environments to improve quality of life.

What is a keystone species?

• A species that has a minor effect on its environment

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

• A species that is the most abundant in an ecosystem

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