Question

This biodiversity boosts oxygen availability?
(A) Ecosystem diversity
(B) Species diversity
(C) Genetic diversity
(D) Cell Diversity

Answer 1

Hint:
There are three levels of Biodiversity: 1)Genetic diversity, 2) Species diversity, and 3) Ecosystem diversity. The biodiversity that boosts oxygen availability is the variety of ecosystems in a given place. An ecosystem is a community of organisms interacting with their physical environment.

Complete step by step answer:
1) Genetic diversity: It is the variety of genes in a population or between populations. Loss of genetic diversity can have negative implications for human welfare. Example: If wild populations close to agricultural species are lost, genetic resources are also lost that are used to improve crop qualities such as disease resistance.
2) Species Diversity: It is the variety of species within a habitat or a region. For example, rainforests and coral reefs have high species diversity and a polluted stream has a low species diversity.
3) Ecosystem Diversity. Bio means life and diversity means variety. So, biodiversity is the various forms of life on earth. It includes all organisms, terrestrial and marine, and also ecosystems to which organisms belong. The range of different cell types is called cell diversity. This arises during the development of the nervous system as a result of acts of cell-intrinsic and extrinsic factors controlling cell fate determination.

Option ‘A’ is correct

Note:
Biodiversity is valuable to us in many ways: 1) Direct economic value- many species are sources of food, many plants are a source of medicine, it provides us with fibres for clothing, wood provides the raw material for shelter and warmth and indirect economic value- importance to biological communities, the stability and productivity of ecosystems.
