AP BIOLOGY

Detailed explanation-1: -Biodiversity refers to every living thing, including plants, bacteria, animals, and humans. Scientists have estimated that there are around 8.7 million species of plants and animals in existence. However, only around 1.2 million species have been identified and described so far, most of which are insects.

Detailed explanation-2: -Species Diversity is simply the number and relative abundance of species found in a given biological organisation (population, ecosystem, Earth). Species are the basic units of biological classification and hence, this is the measure most commonly associated with the term ‘biodiversity’.

Detailed explanation-3: -Biodiversity is all the different kinds of life you’ll find in one area-the variety of animals, plants, fungi, and even microorganisms like bacteria that make up our natural world. Each of these species and organisms work together in ecosystems, like an intricate web, to maintain balance and support life.

Detailed explanation-4: -Usually three levels of biodiversity are discussed-genetic, species, and ecosystem diversity.
