Define the term biodiversity - diversity of important ecological entities that span multiple spatial scales, from genes, to species to communities - biological diversity encompasses all species of plants, animals, and microorganisms, and the ecosystems and processes of which they are part Explain how the terms species, richness, evenness, and diversity are related Species richness: a count of all the different species in a prescribed area Species evenness: a measure of the rareness or c...
