Biodiversity is the variability among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species, and of ecosystems. Teach students how to calculate this number themselves. At site 2, I only detected 25 species and about 200 individuals. This incredible biodiversity is often one of the key reasons for protecting forests— to preserve the vast variety of life on Earth. A study by David Hooper et al. Biodiversity plays an important role in the way ecosystems function and in the services they provide. The key difference between biodiversity and species richness is that biodiversity refers to the variety of life found in a specific place on Earth or the total variety of life on Earth while species richness refers to the number of different species represented in an ecological community, landscape or region.. Biodiversity and species richness are two different terms in ecology. **To request a ref. Cultural services such as recreational, aesthetic and spiritual benefits 4. Biodiversity includes diversity within species (genetic diversity), between species (species diversity), and between ecosystems (ecosystem diversity).
