Ecosystem Diversity can be defined as the variety of different habitats, communities and ecological processes. A biological community is defined by the species that occupy a particular area and the interactions between those species.

- Species Diversity. Every ecosystem contains a unique collection of species, all interacting with each other. …
- Genetic Diversity. Genetic diversity describes how closely related the members of one species are in a given ecosystem. …
- Ecosystem Diversity. …
- Functional Diversity.
In the fields of nature conservation and biodiversity the common meaning of the term ‘habitat’ is a group of animals and plants in association with their environment. Different animals or plants(biodiversity ) live in different habitats.. Thus biodiversity and habitat are related..
What are the levels and types of biodiversity?
Biodiversity is usually explored at three levels – genetic diversity, species diversity and ecosystem diversity. These three levels work together to create the complexity of life on Earth.
What are two levels of biodiversity?
Two levels of biodiversity are : (i) Species diversity : It is a diversity at species level. e.g., amphibian species are found more in the Western Ghats as compared to the Eastern Ghats. (ii) Genetic diversity: A single species shows high diversity at the genetic level over its distribution range.
Which of the following is measured at the species diversity level?
Species diversity is measured by determining the number of species present in a given area or community and calculating how evenly distributed a species is within that community. Indices of species diversity are used which may give more or less weight species that are dominantly found in the landscape.
How are species diversity and genetic diversity different?
How are species diversity and genetic diversity different? Species diversity measures the number of species in the biosphere, while genetic diversity measures the variety of genes in the biosphere, including genetic variation within species. … many habitats and species are at high risk of extinction.

Biodiversity is the sum total of all the varieties of species of plants, animals and micro-organisms living on the earth. It also includes the habitat in which they live.
What is biodiversity class 12?
Biodiversity can be defined as the occurrence of different types of genes, gene pools, species, habitats and ecosystem in a given region. (i) The term biodiversity was given by a socio biologist Edward Wilson to describe the combined diversity at all the levels of biological organisation.
Which of the following levels of biodiversity refers to the different kinds of places where organisms live and interact?
Ecosystem biodiversity refers to the variety of ecosystems, by their nature and number, where living species interact with their environment and with each other.
