From Everests spot to the floor of the Mariana Trench, creatures of one kind or another stop virtually every square inch of the planetary surface.
They adjust the fundamental principle of biological geography, that wherever there is fluidity water, organic molecules, and an energy source, there is life (Wilson 2002). The biosphere is a orbiculate ecosystem composed of living organisms (biota) and the abiotic (non-living) factors from which to drive nutrients.
The biologist Edward O. Wilson who coined the term biodiversity estimated guardedly that in the late 20th century at to the lowest degree 27,000 species are becoming extinct each year(biosphere.
