Question

1) species found only in a particular area is known as ________
​

Answer 1

Answer:

Species found only in a particular area are known as endemic. Endemic species are often endangered. Pandemic species is one that is widely distributed throughout a country or continent. Exotic species are those species that live outside their natural habitat. Thus, the correct answer is option A.

Explanation:

Answer 2

Endemic species are unique to a certain water body, place or region. Neoendemics live in the cradle in which they originated; paleoendemics used to have wider distributions in the past, but occur in relict populations in a more restricted area now. Most endemics occur in water bodies that are both large and old, such as the ancient lakes of Baikal and Tanganyika, but these two conditions are by themselves not sufficient to explain high levels of endemicity. Apart from other ancient lakes, large and ancient river basins such as the Amazon River, harbor many endemics. The same is true for certain hypersaline lakes (Australia) and even temporary pools (South West Africa) in xeric areas and in groundwater.
