Biodiversity: Biodiversity, the variety of life found in a place on Earth or, often, the total variety of life on Earth.

Dec 25, 2017  · Keystone Species Definition. Keystone species are those which have an extremely high impact on a particular ecosystem relative to its population.Keystone species are also critical for the overall structure and function of an ecosystem, and influence which other types of plants and animals make up that ecosystem.

Ecological succession is the process that describes how the structure of a biological community (that is, an interacting group of various species in a desert, forest, grassland, marine environment, and so on) changes over time.Species that arrive first in a newly created environment (such as an island rising out of the sea) are called pioneer species, and they, through their interactions with.

A keystone species is a species that has a disproportionately large effect on its natural environment relative to its abundance. Such species are described as playing a critical role in maintaining the structure of an ecological community, affecting many other organisms in an ecosystem and helping to determine the types and numbers of various other species in the community.
