Answer

(a) Deforestation increases the level of carbon dioxide in the atmosphere. Trees absorb carbon dioxide during photosynthesis, acting as natural carbon sinks. When forests are cleared or burned, this stored carbon is released back into the atmosphere, and the capacity to absorb future emissions is reduced, contributing significantly to climate change and global warming.

(b) Species found only in a particular area are known as endemic species. These organisms have evolved in isolation and adapted to specific local conditions, making them particularly vulnerable to habitat destruction. Examples include the Asiatic lion found only in Gir Forest or the lion-tailed macaque restricted to the Western Ghats. (c) A place where animals are protected in their natural habitat is called a wildlife sanctuary or national park. These protected areas maintain natural ecosystems while safeguarding species from poaching and habitat loss. (d) Satpura National Park is part of the Pachmarhi Biosphere Reserve. (e) Red Data Book contains a record of endangered species, providing detailed information about threatened organisms to guide conservation priorities and protective actions.
