- Genetic Diversity. …
- Ecosystem Diversity. …
- Functional Diversity.
Are habitats part of biodiversity?
Biodiversity is not only the sum of all ecosystems, species and genetic material. Rather, it represents the variability within and among them. … Ecosystem diversity refers to all the different habitats that exist, like tropical or temperate forests, hot and cold deserts, wetlands, rivers, mountains, coral reefs, etc.
What is the variety of habitats and communities within ecosystems called?

What is biodiversity and levels of biodiversity?
Levels 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.
Biodiversity occurs in three different levels: Genetic, Species, and Ecosystem. Genetic diversity refers to the differences within members of a species and their ability to adapt to changes. Species diversity refers to the total number of plant, animal, and insect species that can be found in a particular region.

How is biodiversity distributed?
Biodiversity is not evenly distributed, rather it varies greatly across the globe as well as within regions. Among other factors, the diversity of all living things (biota) depends on temperature, precipitation, altitude, soils, geography and the presence of other species.
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.
What is biodiversity and importance of biodiversity?
Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services.
Which level of diversity is refers to the variety of habitats?
Ecosystem Diversity can be defined as the variety of different habitats, communities and ecological processes.
Which level is most commonly meant by biodiversity?
Species diversity is most commonly meant by biodiversity.
Why is biodiversity important at the community level?
Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. … Healthy ecosystems can better withstand and recover from a variety of disasters.
What does a community include?
A community is a social unit (a group of living things) with commonality such as norms, religion, values, customs, or identity. Communities may share a sense of place situated in a given geographical area (e.g. a country, village, town, or neighbourhood) or in virtual space through communication platforms.
