The subject of species richness encompasses a wide range of important elements. What is Species Diversity? There are two constituents of species diversity: Species richness: Number of different species present in an ecosystem. Tropical areas have greater species richness as the environment is conducive for a large number of species Species evenness: Relative abundance of individuals of each of those species. Furthermore, biodiversity Hotspots – 2 Main Qualifying Criteria - BYJU'S. Additionally, biodiversity is referred to as the variation of plant and animal species in a particular habitat. Species evenness and species richness form the major components of biodiversity.
Biodiversity Definition - BYJU'S. Biodiversity in India India is one of the most diverse nations in the world. It ranks ninth in terms of plant species richness.
Another key aspect involves, two of the world’s 25 biodiversity hotspots are found in India. It is the origin of important crop species such as pigeon pea, eggplant, cucumber, cotton and sesame. BYJU'S Online learning Programs For K3, K10, K12, NEET, JEE, UPSC .... Ecologists can estimate the total number of species on Earth through a statistical comparison between the species richness of a well-studied group of insects in tropical and temperate regions. Later, these ratios are extrapolated with groups of other plants and animals to estimate the net species richness found on Earth.
This is yet another reason for increased species diversity. Equally important, solar energy adds to higher productivity and helps in increasing biodiversity in the tropics. Species-Area Relationship The graph between species richness and area for a variety of taxa is a rectangular hyperbola. The diagram depicts the same. Species richness is the count of different species in a given area..
Species richness is the biodiversity of a given area. Habitat A covers an area of 250 sq. km and hosts around 50 different species of organisms. Habitat B also covers an equal stretch of area and is the home to 75 different species of organisms.

Latitudinal gradient - BYJU'S. What is latitudinal gradient? As we move from the equator to the poles, the biodiversity and species richness decreases.
This is known as latitudinal gradient. Who observed that within a region, species richness increased with ....
