Explanation
Community and ecosystem diversity is of three types- alpha, beta and gamma.
Alpha diversity is the species diversity in a given community or habitat, alpha diversity is dependent upon species richness and evenness or equitability.
Beta diversity is biodiversity, which appears in a range of communities due to the replacement of species with the change in community or habitat due to the presence of different micro-habitats, niches and difference in environment conditions.
Gamma diversity is diversity present in ranges of communities as represented by the diversity of habitats or ecosystems over a total landscape or geographical area.
Biodiversity is not uniform on the Earth. It varies with the
change in latitude or altitude.
Biodiversity increase,
when we move from high to low latitude (i.e., from the poles to the equator)

All of the above
Explanation
Conservation means preservation from loss, waste or degradation of a resource, so as to last indefinitely.
Management of a resource is controlling the use of the resource in such a way so as to provide sustained and equitable availability. The two are important because exhaustible resources are undergoing rapid depletion.
Lifetime of a resource is the period along the time scale up to which its availability for human use is assured on global basis.
Depletion time is the period along with the timescale when the availability of resources will decrease to such an extent that it is unable to meet the human requirements.

Explanation
In situ conservation is on-site conservation or the conservation of genetic resources in natural populations of plant or animal species, such as forest genetic resources in natural populations of tree species. It is the process of protecting an endangered plant or animal species in its natural habitat, either by protecting or cleaning up the habitat itself, or by defending the species from predators. It is applied to conservation of agricultural biodiversity in agro ecosystems by farmers, especially those using unconventional farming practices. Insitu conservation includes national parks, sanctuary and biosphere reserve.
Botanical gardens comes under exsitu conservation. Thus, option C is correct and other options are wrong.

Bergman's law
Explanation
The climatic conditions in a particular area regulate the physiological and the morphological characteristics of plants or animals. Allen's rule is a biological rule by Joel Asaph Allen in 1877. It states that the organism adjusts in the given climatic conditions by either minimizing exposed surface area to minimize heat loss in cold climates or maximizing exposed surface area to maximize heat loss in hot climates. The rule predicts that endotherms from hot climates usually have ears, tails, limbs, snouts, etc that are long and thin, while equivalent animals from cold climates usually have shorter and thicker versions of those body parts.
Allen's rule predicts that endothermic animals with the same body volume should have different surface areas that will either aid or impede their heat dissipation.

Africa and Asia
Explanation
Rhinoceros often abbreviated as rhino, is a group of five extant species of odd-toed ungulates in the family Rhinocerotidae. Two of these species are native to Africa and three to Southern Asia.Rhinoceros are killed by humans for their horns, which are bought and sold on the black market, and which are used by some cultures for ornamental or traditional medicinal purposes. East Asia, specifically Vietnam, is the largest market for rhino horns. By weight, rhino horns cost as much as gold on the black market. People grind up the horns and then consume them believing the dust has therapeutic properties. The horns are made of keratin, the same type of protein that makes up hair and fingernails. Both African species and the Sumatran rhinoceros have two horns, while the Indian and Javan rhinoceros have a single horn. The IUCN 'Red List' identifies three of the species as critically endangered.

Panthera tigris
) is the largest cat species, reaching a total body length of up to 3.38 m (11.1 ft) over curves and weighing up to 388.7 kg (857 lb) in the wild. Its most recognizable feature is a pattern of dark vertical stripes on reddish-orange fur with a lighter underside. The species is classified in the genus Panthera with the lion, leopard, jaguar and snow leopard. Tigers are apex predators, primarily preying on ungulates such as deer and bovids. The wild buffalo (Bubalus arnee), also called Asian buffalo and Asiatic buffalo, is a large bovine native to the Indian Subcontinent and Southeast Asia.
Tigers will be mostly killed by wild buffaloes, when they both fight. So, a tiger will have to think twice before attacking wild buffalo.

Explanation
A biodiversity hotspot is a biogeographic region with a significant reservoir of biodiversity that is under threat from humans. To qualify as a biodiversity hotspot on Myers 2000 edition of the hotspot-map, a region must meet two strict criteria: it must contain at least 0.5% or 1,500 species of vascular plants as endemics, and it has to have lost at least 70% of its primary vegetation. Around the world, 25 areas qualify under this definition, with nine other possible candidates. These sites support nearly 60% of the world's plant, bird, mammal, reptile, and amphibian species, with a very high share of endemic species.
