How does over exploitation of beneficial species affect biodiversity ? Explain with the help of one example.

The main cause of extinction of species from tropical area is : (a) Over - exploitation (b) Deforestation (c) Alien species invasion (d) More than one option is correct

There are four major causes of accelerated rates of species extinction, which are collectively called as 'the evil quartet'. Which one of the following is not included in 'the evil quartet' ? (a) Over exploitation (b) Pollution (c) Co-extinctions (d) Alien species invasions

Island biogeography theory states that the number of species on an island is determined by immigration rates of new species to the island and extinction rates of species on the island. Immigration rates to an island decline as its distance from the mainland increases adn extinction rates decreases with increasing island size. when the immigration and extinction rates on an island are equal, the number of species on the island reaches equilibrium. Which of the following gives the correct combination of distance (near and far) and area (small and large of islands where species (S_(1) -S_(4)) occur ?
