Which of the following regions of the globe exhibits highest species diversity?
1 Madagascar
2 Himalayas
3 Amazon forests
4 Western Ghats of India
Explanation:
Exp: - Amazon forests occupy the tropical belt with climatic conditions being hot and humid - This condition is responsible for a variety of plant growth followed by the dependent heterotrophic. - Over 3 million species live in the rainforest, over 2,500 species help create and substain this vibrant ecosystem. - The Amazon rainforest is known to be home to 427 mammal species, 1,300 bird species, 378 species of reptiles and more than 400 species of amphibians.

According to Robert May, the global species diversity is about
1 20 million
2 50 million
3 7 million
4 1.5 million
Explanation:
According to Robert May, global species diversity is about 7 million. - Species diversity refers to the different species present in a particular area. - It has two components :- (i) species richness (ii) species evenness. - Species richness represents the number of species found in an area, whereas species evenness in the relative abundance of each species.

Beta diversity is diversity
1 In a community
2 Between communities
3 In a mountain gradient
4 On a plain
Explanation:
In ecology, $\beta$-diversity is the ratio between regional and local species diversity. It was introduced by R. H. Whitteker in 1960. There are three types of diversity in community and ecosystem :- - $\alpha$ Diversity- The total No of species present in an area or ecosystem. - $\boldsymbol{\beta}$ Diversity- A comparison of diversity between ecosystem. It means not present in both ecosystem. count only unique species. - $\gamma$ Diversity- Counts of the overall diversity for different ecosystems within a large region.

One of the following statements is incorrect with reference of biodiversity. Identify it.
1 The areas with very few plant and animal species (low species richness) with no threatened species are called biodiversity hotspots
2 Biodiversity increases from higher altitudes to lower altitudes
3 Biodiversity decreases from the equator to polar regions
4 Depletion in genetic diversity of crop plants is mainly due to the introduction of better varieties with high yield, disease resistance, etc
Explanation:
Biodiversity hotspots are areas which are rich in animal or plant species or high degree of biodiversity. - Biodiversity hotspots are biogeographic regions which are rich in reservoirs of plants and animals. These are also threatened by habitat loss and other human activities. They are determined by mainly three factors. (1) A number of species diversity. (2) The degree of the endemism. (3) The degree of the threat to habitat due to its degradation and fragmentation.

Which of the following has highest diversity in India?
1 Mango
2 Dolphin
3 Tiger
4 Orchids
Explanation:
Among the following, mango has highest diversity in India. Inflorescence is terminal or axillary panicle Flower actinomorphic, cotyledon thick with little or no endosperm and curved embryo. Fruit is usually drupe, mesocarp resinous \& fleshy in Mangifera. Some time nut (anocardium) - India has more than 1,000 variety of mango and 50,000 genetically different strains of rice.
