Great biodiversity exists on our planet. Millions of living plants and animal species are flourishing on Earth. An approximate of 1.7 million organisms are known to exist. Out of them, 309 mammal species are recorded in India.

Indri indri lemur also known as babakoto, is the largest living lemur on Earth. It as a head-and-body length of about 64–72 cm (25–28 in) and a weight of between 6 to 9.5 kg (13 to 21 lb). It occurs in Madagascar. It plays an important part in the myths of the residents of Madagascar, and legends with various stories in existence accounting for its origin. According to IUCN, it is classified as a critically endangered species.

India is one of the richest countries when it comes to the diversity of plant species. Around 45,000 plant species are estimated to be present in India. There are eight main florist regions in India which are Western Himalayas, Eastern Himalayas, Assam, Indus plain, Ganges plain, the Deccan, Malabar, and the Andaman Islands. So, great efforts for protecting the immense biodiversity should be done.

Species diversity decreases from equator to poles. The reason lies behind the fact that the conditions for the survival of species at poles become unfavorable. The Equator has favorable conditions for the survival of wildlife. Good vegetation, sunlight, and habitat these factors are responsible for great biodiversity at the equator.

Species diversity increases towards the equator. The two main reasons are phylogenetic niche conservatism and ecological productivity. The relatively high temperatures in the tropics generate and maintain high diversity. However, the tropical rainforests in developing countries are getting cleared nowadays, which is leading to a great loss of biodiversity.

Great biodiversity exists on our planet. Millions of living plants and animal species are flourishing on Earth. An approximate of 1.7 million organisms are known to exist. New species are getting discovered and recorded every year. Indian share in global species diversity is about 8%.

Species diversity is the number of different species that are represented in a given community. In India, rice has the largest species diversity or variety. India has 6,000 species variety of rice. The number has greatly reduced from before. The commonest rice is basmati rice.
