Question

Describe in brief about biodiversity in India.

Answer 1

Biodiversity is the variety and differences among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are a part. This includes genetic diversity within and between species and of ecosystems. Thus, in essence, biodiversity represents all life. India is one of the mega biodiversity centres in the world and has two of the world's 18 ‘biodiversity hotspots’ located in the Western Ghats and in the Eastern Himalayas (Myers 1999). The forest cover in these areas is very dense and diverse and of pristine beauty, and incredible biodiversity.

According to an MoEF Report (1996), the country is estimated to have over 45,000 plant species and 81,000 animal species representing 7% of the world’s flora and 6.5% of its fauna. The 1999 figures are 49,219 plant species representing 12.5% and 81,251 animal species representing 6.6%.

The sacred groves of India are some of the areas in the country where the richness of biodiversity has been well preserved. The Thar desert and the Himalayas are two regions rich in biodiversity in India. There are 89 national parks and 504 wildlife sanctuaries in the country, the Chilika Lake being one of them. This lake is also an important wetland area.

Over the last century, a great deal of damage has been done to the biodiversity existing on the earth. Increasing human population, increasing consumption levels, and decreasing efficiency of use of our resources are some of the causes that have led to overexploitation and manipulation of ecosystems. Trade in wildlife, such as rhino horn, has led to the extinction of species. Consequences of biodiversity loss can be great as any disturbance to one species gives rise to imbalance in others. In this the exotic species have a role to play

Biodiversity➫ The number and types of plants and animals that exist in a particular area.

♦ It is the existence of a wide variety of plant and animal species living in.

♦ Greater species diversity ensures natural sustainability for all life forms.

♦ It boosts ecosystem productivity where each species, no matter how small.

➧ Types of Biodiversity are:-

[1] Genetic Diversity:-

❱ The total number of genetic characteristics in the genetic makeup of a species. 

[2] Species  Diversity:-

❱ The number of different species that are represented in a given community.

[3] Ecosystem  Diversity:-

❱ The the variety of different ecosystems within an area.

➧ Importance of Biodiversity:-

❱ It Increase ecosystem productivity.

❱ It offers:-

♦ Fish
♦ Food
♦ Harvest
♦ Silviculture
♦ Livestock

❱ It provides functioning ecosystems that:-

♦ Pest control
♦ Supply 0xygen
♦ Clean air & Water
♦ Pollination of plants
♦ Wastewater treatment
♦ Ecosystem services

➧ We can protect Biodiversity by:-
