CONCEPTS OF BIODIVERSITY CONCEPTS OF BIODIVERSITY 1.Human Population Growth 2. While biodiversity has been accepted as a core goal of modern conservation science, there is some scepticism in the philosophical literature toward the utility of this concept. Each ecosystem consists of organisms from many different species, living together in a region connected by the flow of energy and nutrients. Ecological diversity refers to the variability among the species of plants and animals living together and connected by flow of energy and cycling of nutrients in different ecosystems or ecological complexes. Biodiversity is the variation among living organisms from different sources including terrestrial, marine and desert ecosystems, and the ecological complexes of which they are a part.. People go to far off places to enjoy the natural surroundings and wildlife. Biodiversity conservation refers to the protection, preservation, and management of ecosystems and natural habitats and ensuring that they are healthy and functional.
