Statement A : When a species becomes extinct, the plant and animal species associated with it in an obligatory way also become extinct. Statement B : When a host fish species becomes extinct, its unique assemblage of parasites also meets the same fate.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
Both the statements are correct. When a species becomes extinct, the plant and animal species associated with it in an obligatory way also become extinct. When a host fish species becomes extinct, its unique assemblage of parasites also meets the same fate.

Select the incorrect match:
1 Lungs of the planet - Amazon rain forest
2 Extinction due to over exploitation - Passenger pigeons
3 Nile perch - Cichlid fish
4 David Tilman - Rivet Popper hypothesis
Explanation:
Ecologist Paul Ehrlich gave rivet popper hypothesis to help understand the contribution of species richness. He compared each species with rivet in the body of an airplane. (i). this hypothesis explains that ecosystem to be an airplane and the species to be the rivets joining all parts together (ii) If every passenger travelling in the airplane start taking home (causing a species to become extinct), initially it may not affect flight safety (proper functioning of ecosystem), but over a period of time the plane becomes weak and dangerous (species become endangered and then extinct).

The most important reason for decrease in biodiversity is
1 Habitat pollution
2 Introduction of exotic species
3 Over- exploitation
4 Habitat destruction
Explanation:
Habitat loss and fragmentation: This is the most important cause driving animals and plants to extinction. The most dramatic examples of habitat loss come from tropical rain forests.
