Which of the following best describes the term "biodiversity"?

The term "biodiversity" is best described as the variety of life in a particular habitat or ecosystem because it encompasses the different species—plants, animals, fungi, and microorganisms—and the genetic diversity within those species, as well as the variability of ecosystems. Biodiversity is crucial for maintaining ecological balance, as it ensures that ecosystems can function effectively and respond to environmental changes.

While you may consider factors such as endangered species or forest land relevant to ecological health, they don't capture the full scope of what biodiversity entails. Endangered species represent only a fraction of the total biodiversity and focus on conservation issues, while the amount of forest land pertains specifically to land use and environmental management. Similarly, climate changes are related to environmental conditions but do not reflect the complexity of life forms and their interactions within ecosystems.
