Question

The term Biodiversity is popularized by
A. Odum
B. Paul Ehrlich
C. Edward Wilson
D. Tilman

Answer 1

Hint: ‘Biodiversity’ is meant by the diversity found in living organisms. In this world, various species of microorganisms, plants, and animals are found. So the diversity found in living organisms is known as biodiversity.
 Each and every species has a different organization, character, and biological importance. Variations are found more in organisms of different categories of classification. For example, we can differentiate cats and frogs because these belong to class mammals and amphibians.

Complete answer:
The term Biodiversity was given by W.G. Rosen.
But this term was popularized by Edward Wilson. He defined biodiversity for different levels of the organization like; Genetic variation, Species variation, and ecological variations. He was a socio-biologist.
Total known species in this world are more than 1.5 million.
David Tilman gave this fact that biodiversity is increased by productivity.
Paul Ehrlich proposed the Rivet popper hypothesis. According to this hypothesis, some species are as important for an ecosystem, as the rivets are important in the body of a plane.
He pioneered work on ecosystems. He also gave the universal model for energy flow in the food chain (in 1966). This model was accepted.

So, the answer is option C. Edward Wilson.

Note: Biodiversity has a very important role in our life. From the past few years, biodiversity has been affected very badly. The destruction of the natural habitat of many living organisms, over-exploitation, the introduction of various foreign species, co-extinction, etc. is the main reason for the extinction of various species.
Many species of commercial importance have been extinct. For a balanced and healthy ecosystem, all different types of organisms are Important. Many species of great Amazon forest have been extinct due to habitat fragmentation.
