BIODIVERSITY

What does biodiversity refer to?

• Types of clouds in the sky

• Number of planets in the solar system

• Variety of life forms on Earth

• Variety of cars on the road

Why is biodiversity important?

• Biodiversity is only important for aesthetics

• Biodiversity is important for ecosystem stability, resources, food chains, and resilience.

• Biodiversity is irrelevant for human survival

• Biodiversity has no impact on ecosystems

Name three different types of biodiversity.

• habitat diversity

• genetic diversity, species diversity, ecosystem diversity

• environmental diversity

• population diversity

How does deforestation affect biodiversity?

• Deforestation has no impact on biodiversity

• Deforestation increases biodiversity by creating new habitats

• Deforestation only affects a few species, not overall biodiversity

• Deforestation reduces biodiversity by destroying habitats and food sources for many species.

What is an ecosystem?

• An ecosystem is a group of nonliving components in a specific environment.

• An ecosystem is a single organism in a specific environment.

• An ecosystem is a term used only in marine biology.

• An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system.

Explain the difference between a food chain and a food web.

• Food chains are more complex than food webs in terms of the number of organisms involved.

• In a food chain, energy and nutrients flow in a single direction, while in a food web, energy and nutrients flow in multiple directions.

• Food chains involve only producers and consumers, while food webs include decomposers.

• In a food chain, energy and nutrients flow bidirectionally, while in a food web, they flow unidirectionally.

What is an endangered species?

• An endangered species is a species that is abundant.

• An endangered species is a species that is thriving.

• An endangered species is a species that is at risk of extinction.

• An endangered species is a species that is overpopulated.

How can we help protect biodiversity?

• Destroy natural habitats, promote pollution, reduce awareness

• Increase pollution, destroy natural habitats, ignore sustainable practices

• Spread awareness, reduce pollution, promote unsustainable practices

• Preserve natural habitats, reduce pollution, promote sustainable practices, and raise awareness.

Name three ways in which humans negatively impact biodiversity.

• deforestation

• conservation

• climate change

• habitat destruction, pollution, overexploitation

What are some examples of keystone species?

• Sea otters, beavers, wolves

• Eagles

• Lions

• Dolphins
