 Which area out of a to d shows maximum species diversity?

  • b

  • c

  • d

  • a

Solution

C.

d

Habitat is the place where an organism live. The population has been defined as a collective group of organisms of the same species occupying a particular place at a particular time. In the given table area d has maximum species diversity, as there are 10 species (A-J) reside in 12 habitats, while in area c the 10 species reside in 13 habitats so, exhibit less diversity than area d.
