Explanation: The Community Forest Resource rights under Section 3(1)(i) of the Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act (commonly referred to as the Forest Rights Act or the FRA) provide for recognition of the right to “protect, regenerate or conserve or manage” the community forest resource. These rights allow the community to formulate rules for forest use by itself and others and thereby discharge its responsibilities under Section 5 of the FRA. It is important as it recognises the community’s right to use, manage and conserve forest resources, and to legally hold forest land that these communities have used for cultivation and residence. It also underlines the integral role that forest dwellers play in sustainability of forests and in conservation of biodiversity. Simlipal National Park in Odisha is the first national park to recognise Community Forest Resource rights. Hence, all statements are correct.

Answer: (D)
Explanation: The most important key elements that lead to so much variation in the physical and chemical conditions of different habitats ones are temperature, water, light and soil. We must remember that the physico-chemical (abiotic) components alone do not characterise the habitat of an organism completely; the habitat includes biotic components also – pathogens, parasites, predators and competitors – of the organism with which they interact constantly. Hence, all are correct.
