Answer:

The ecological role of prokaryotes is : fixing nitrogen to be used by producers, producing organic carbon of the atmospheric oxygen.

Step-by-step explanation:

1. Decomposers: Organisms that break down dead organisms as well as waste products to unlock the supplies of carbon, nitrogen and other elements. Releasing CO₂, breaking downg carbon into minerals to be released back into the environment.

2. Producers: Converting CO₂ into O₂, main food source of life.

3. Nitrogen fixers: Prokaryotes that converts atmospheric N₂ into usable compounds (nitrates, ammonium) for plants to be able to metabolize.

4. Pathogens: Can be diseases that affect certain species and change the environment.

5. Various symbioses:

  • Mutualistic bacteria: gut bacteria aid in digestion.
  • Pathogenic bacteria: causes illness.
  • Bioremediation: prokaryotes that can remove polluants form the air, soil, or water.
