A species is considered to be extinct if it has NOT been seen in its natural habitat for –
Correct Answer:
(D)
50 years
According to the definition provided by the International Union for Conservation of Nature, a species not seen during the last 50 years is considered to be extinct.
Ques: 2
Which one of the following is not responsible for the extinction of a species?
Correct Answer:
(A) Broad niche
In ecology, the term “niche” describes the role an organism plays in a community. A species’ niche encompasses both the physical and environmental conditions it requires (like temperature or terrain) and the interactions it has with other species (like predation or competition). In general, species that have narrow or limited niches are considered to be specialist species. Koalas which feed only on leaves from eucalyptus trees in Australia, are an example of a specialist species. Species with broader niches, like coyotes or raccoons are considered generalists.
