What defines biodiversity?
The term biodiversity (from “biological diversity”) refers to the variety of life on Earth at all its levels, from genes to ecosystems, and can encompass the evolutionary, ecological, and cultural processes that sustain life.
What are the 4 types of biodiversity?
Four Types of Biodiversity
- 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.
What is the aim of biodiversity?
Biodiversity is the variety of living organisms on the earth. The aim of conservation of biodiversity is to protect, preserve and manage natural resources.

What are the causes and effects of biodiversity?
Habitat destruction is a major cause of biodiversity loss. Habitat loss is caused by deforestation, overpopulation, pollution, and global warming. Species that are physically large and those living in forests or oceans are more affected by habitat reduction.
What are 5 benefits of biodiversity?
Support a larger number of plant species and, therefore, a greater variety of crops. Protect freshwater resources. Promote soils formation and protection. Provide for nutrient storage and recycling.
Why is it so important to protect biodiversity?
Healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food. Biodiversity is the key indicator of the health of an ecosystem. A wide variety of species will cope better with threats than a limited number of them in large populations.
How does biodiversity affect human life?
Biodiversity supports human and societal needs, including food and nutrition security, energy, development of medicines and pharmaceuticals and freshwater, which together underpin good health. It also supports economic opportunities, and leisure activities that contribute to overall wellbeing.
Does biodiversity have value?

The six major values are: (a) Total Environmental Value (TEnV), (b) Primary Value (PV), (c) Total Economic Value (TEV), (d) Use Value (UV), (e) Direct Use Value (DUV), (f) Indirect Use Value (IUV), and (g) Ethical and Aesthetic Values.
How will you classify the value of biodiversity?

What is a direct value of biodiversity?
Direct values include the ways in which biodiversity is used or consumed by man e.g. fishery and forestry products, as well as the ways in which it affects mankind through its ecological processes e.g. watershed protection or the role of vegetation in the carbon and water cycles.
What are the direct economic benefits of biodiversity?
Biodiversity Underpins Economic Activity Food production relies on biodiversity for a variety of food plants, pollination, pest control, nutrient provision, genetic diversity, and disease prevention and control. Both medicinal plants and manufactured pharmaceuticals rely on biodiversity.
What is the direct and indirect value of biodiversity?
Biodiversity encompasses the variety of plant and animal species in a particular habitat or ecosystem. Direct values of biodiversity include an actual economic impact that can be gained through the various life forms. Indirect values of biodiversity reflect the intrinsic value of the land.
What is the difference between direct and indirect biodiversity?
Direct use value of biodiversity is every living organism has an important rules for sustainability and nourishment of nature and ecosystem. Indirect use value of biodiversity is that every living organism is dependent on other organisms indirectly.
