Researchers generally accept 3 levels of biodiversity: genetic, species, and ecosystem. These levels are all interrelated yet distinct enough that they can be studied as 3 separate components. Some researchers believe that there are fewer or more levels than these, but the consensus is that 3 levels is a good number to work with. Most studies, focus on the species level, as it is the easiest to work on both conceptually and in practice.  | | Biodiversity describes the variety of life on Earth from microorganisms to whales, along with the habitats they depend upon. |
