What is meant by species diversity?
Species diversity is the number of different species that are represented in a given community (a dataset). … Taxonomic or phylogenetic diversity is the genetic relationship between different groups of species. Species evenness quantifies how equal the abundances of the species are.
What are the 3 types of species diversity?
Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity. Genetic diversity is all the different genes contained in all individual plants, animals, fungi, and microorganisms.
What is species diversity explain with an example?
Species diversity is defined as the number of species and abundance of each species that live in a particular location. … Abundance is the number of individuals of each species.

What do you mean by species diversity name two measures of species diversity?
The two important measures of species diversity are : (i) Species richness. It refers to the number of species per unit area. (ii) Species evenness. It refers to the relative abundance with which each species is represented in an area.
How can you say species diversity affect biodiversity?
Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.
What is the difference between species and organism?
As nouns the difference between organism and species
is that organism is (biology) a discrete and complete living thing, such as animal, plant, fungus or microorganism while species is a type or kind of thing.
What is the difference between species diversity and species composition?
Species diversity has two primary components: species richness (the number of species in a local community) and species composition (the identity of the species present in a community). … In the case of plants, all species may utilize the same suite of resources (space, light, water, soil nutrients, etc.)
