However, no scientific evidence was present at that time to prove the idea of evolution. All living organisms have what is called a fundamental niche.The fundamental niche includes all possibilities open to the organism within that environment: all possible sources of food, all open behavioral roles in the environment, and all suitable habitats available to it.For example, a black bear (Ursa americanus) is a broadly distributed, … No two individuals belonging to the same species are exactly similar. This could be structural differences (between a tree and an ant) or functional […] It is the biodiversity observed within a … Biomass, the weight or total quantity of living organisms of one animal or plant species (species biomass) or of all the species in a community (community biomass), commonly referred to a unit area or volume of habitat.The weight or quantity of organisms in an area at a given moment is the standing crop. Species Diversity. AQA A-Level Biology Revision Notes (Year 2) Module 7 (Population, Evolution, Inheritance) Revision Notes What is a species? Some members of the same species may look very different from each other. For example, in the species of human beings, each human shows a lot of diversity in comparison to another human. People living in different regions show a great level of variation. A primary succession starts with a pioneer species colonising bare rock or sand.

Many scientists before Darwin stated that a species evolves from an ancestor or from a different species. Biodiversity (b) explain how biodiversity may be considered at different levels; habitat, species and genetic. Realized Niche .
