1 - f Biodiversity is the variety of organisms existing on the earth, their interrelationships, and their relationship with the environment. Biodiversity also refers to the variety of living species on Earth, including plants, animals, bacteria, and fungi. Biodiversity provides functioning ecosystems that supply oxygen, clean air, and water, pollination of plants, pest control, wastewater treatment, and many ecosystem services. 2 - i Large areas of protected land for conservation of wildlife, plant and animal resources, and traditional life of the tribals living in the area. Biosphere reserves include terrestrial, marine, and coastal ecosystems. They are learning places for sustainable development. 3 - h A national park is a large area protected and maintained by the government. It is meant for the conservation of wildlife. It also preserves the places of scientific interest. They preserve flora as well as fauna. Jaldapara National Park is to conserve Fauna named as Indian rhinoceros and Kanha National Park to conserve Barasingha or swamp deer. 4 - e A wildlife sanctuary is a protected area of land created for the protection of wild animals in their natural environment. Capturing, poaching is strictly prohibited. People living in wildlife sanctuaries are allowed to do certain activities such as grazing their livestock, collecting medicinal plants, firewood, etc. 5 - b The biosphere refers to the part of the earth in which living organisms exist. It is a zone where all the living and non-living components interact with each other to support the life system. 6 - g Endangered species are those species that are facing the risk of extinction. Their population is declining due to various factors such as poaching, overhunting, loss of habitat, etc. The giant panda, tiger, whooping crane, blue whale, etc arean example of endangered species. 7 - a Endemic species are plants or animals exclusive to an area. For example, Nilgiri Tahr is endemic to Nilgiri Hills and the southern portion of the Western & Eastern Ghats in the states of Tamil Nadu and Kerala in Southern India. Endemic species are often endangered, so it is important to save the species. 8 - c Red Data Book is the document established b y the IUCN that contains a record of endangered species of plants and animals. It helps to prot e ct extinct specie s, hence preserving the biodiversity in a particular region. 9 - d Extinct species are those species that no longer exist anywhere in the world. They have vanished from the earth due to various reasons such as overhunting, loss of habitat, poaching, etc. Dodo, Great Auk, Stellers Sea Cow, Tasmanian Tiger, etc are a few examples oe extinct species.
