Question

Contrast two ways that biologists have defined and measured biodiversity. Explain how a community can be diverse in one sense without being diverse in another sense.

Answer 1

Biodiversity is the variety and varieability present on earth.it includes the variation present at the genetic-species-ecosystem level.variability among living organisms from all sources including terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are a part; this includes diversity within species, between species and of ecosystems.

Measurement of biodiversity-it can be measured based on species richness(that includes how much variety of species are available) plus species evenness(equal distribution of species).

A community can be diverse in one sense that it has a significant population of for eg x group.but on the other hand it can be non diverse as it does not have any no other group in that significant value or nos.it can also not have sexual diversity.
