Answer:
Bioremediation uses micro-organisms to reduce pollution through the biological degradation of pollutants into non-toxic substances. This can involve either aerobic or anaerobic micro-organisms that often use this breakdown as an energy source.
I am assuming that since you are in a biology class, you are looking for the answer: cells.

In the Nitrogen cycle there are basically four steps and bacteria is involved in three steps of the N-cycle namely – Nitrogen fixation, Ammonification and De-Nitrification.
The Decomposers bacteria are involved in the ammonification process, where they convert organic waste, rich in nitrogen into simpler compounds usually ammonia which is further broken down into nitrite and nitrate. This process usually occurs in the absence of light and oxygen by anaerobic/facultative bacterias.
Answer:
The best answer is A-energy efficiency
Explanation:
Energy efficiency is a positive contribution made by science to benefit the user (less costs of electricity) and the planet.
