Which of the following diversity boosts the availability of oxygen?a.Species diversityb.Cell diversityc.Genetic diversityd.Ecosystem diversity

The correct answer is d. Ecosystem diversity.

Here's why:

a. Species diversity refers to the variety of different species within a particular area. While different species may contribute to the production of oxygen (like plants and certain bacteria), the diversity itself doesn't directly boost the availability of oxygen.

b. Cell diversity refers to the variety of cell types within an organism. This doesn't have a direct impact on the availability of oxygen in the environment.

c. Genetic diversity refers to the total number of genetic characteristics in the genetic makeup of a species. It doesn't directly affect the availability of oxygen.

d. Ecosystem diversity, however, refers to the variety of different ecosystems on Earth, each of which has its own balance of species. The more diverse ecosystems we have, the more balanced our global ecosystem is. This balance includes the oxygen cycle, where plants in many ecosystems produce oxygen. Therefore, ecosystem diversity boosts the availability of oxygen.
