Question

The endangered largest living lemur Indri indri is an inhabitant of
A. Sri Lanka
B. Madagascar
C. Mauritius
D. India

Answer 1

Hint: The lemur is a primate species and they are majorly found in the African continent in the countries in the East African region.

Step by step answer:The word Indri means ‘there it is’. Indri is the largest known species of Lemur. But they are categorized as endangered and left around only 10,000 in number. Endangered species are those which are on the verge of extinction and whose population numbers have been reduced to an alarming level.
-Option A is Sri Lanka that lies in the Southern Asian subcontinent. It is home to Gray slender Loris or Loris lydekkerianus Lemur species. Although Sri Lanka is considered as one of the Biodiversity hotspots on the Earth, the Indri indri species is not inhabitant here.
-Option B is Madagascar. It is one of the places having dense lowland Rainforests. It lies on the coast of East Africa and is popularly known for the native species of the largest living lemur Indri indri.
-Option C is Mauritius and is located on the south-eastern coast of the African continent in the Indian Ocean. As it is isolated land it is comparatively low in wildlife diversity but is native to many endangered and exotic species. But Indri lemur species are not found here.
-Option D is India. It is a country in South Asia, and it is also considered one of the major biodiversity hotspots but is not an inhabitant of Indri.
Hence, the correct option is B, Madagascar

Note: There are similar location factors of Madagascar and Mauritius, it is Madagascar that serves as the only habitat for Indri. The Indri species are endangered as a result of over-population, urbanization, and industrialization. Worldwide 15,500 and more species are being endangered. Loss of biodiversity or exotic species leads to less resistance to environmental disturbances and thus should be taken care of.
