Biodiversity encompasses the variety of life on Earth, including all species, ecosystems, and genetic variation.

Habitat diversity is not a major type of biodiversity. The three major types of biodiversity are ecosystem diversity, species diversity, and genetic diversity.

Extinction is the term used to describe the loss of biodiversity. It occurs when a species is no longer able to survive and reproduce in its environment.

Natural selection is not a major cause of biodiversity loss. The three major causes of biodiversity loss are habitat destruction, pollution, and climate change.

Invasive species is the term used to describe the process of introducing a non-native species into an ecosystem.

Monarch butterfly is not an example of an invasive species. Kudzu, zebra mussels, and Asian carp are all examples of invasive species.

Endangered species is the term used to describe a species that is at risk of extinction.

Bald eagle is not an example of an endangered species. Giant panda, blue whale, and African elephant are all examples of endangered species.

Extinct species is the term used to describe a species that is no longer in existence.

Steller's sea cow is not an example of an extinct species. Dodo bird, passenger pigeon, and thylacine are all examples of extinct species.

Conservation is the term used to describe the process of protecting and restoring biodiversity.

Introducing invasive species is not an example of a conservation effort. Creating protected areas, reducing pollution, and promoting sustainable agriculture are all examples of conservation efforts.

Sustainability is the term used to describe the sustainable use of natural resources.

Deforestation is not an example of a sustainable practice. Using renewable energy sources, reducing waste, and recycling are all examples of sustainable practices.

Biodiversity is the term used to describe the interconnectedness of all living things.
