Which of the following involves metabolic cooperation among prokaryotic cells?
a. binary fission c. biofilms
b. endospore formation d. photoautotrophy

c. Biofilm

Explanation:

Metabolic cooperation between prokaryotes

allows them to use the resources that they could not use when they are living as single cell. Bio film is the example of the metabolic cooperation.

Bio films are formed by the colonizing of single type of prokaryote such as bacteria and they facilitate the growth of other bacteria on the surface by secreting the substances essential for their growth.

Hence, the correct option is (c) biofilms.

humans can cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of invasive species (such as new predators and food competitors), overhunting, and other influences. explosive, unsustainable human population growth is an essential cause of the extinction crisis.
