Answer:
They provide food for living things.
Some aid in the nitrogen cycle.
The most important is that they decompose organic material.
Explanation:
In order for plants to assimilate nitrogen directly into their system, the nitrogen must be in the form of nitrates. Nitrogen in the air and ammonia from decayed matter in the soil is converted to ammonium by decomposers and nitrogen-fixing bacteria. The ammonium is further nitrified to nitrates by nitrifying bacteria. Finally, the nitrates can then absorbed by the plants.
The answer is C.
PS. This lead to his study about evolution. Darwin in now dubbed as the father of evolution.

Cyanide, raw sewage, petroleum from shipping accidents, and detergents are all examples of Water pollution.
Water pollution is the contamination of water bodies by substances like Cyanide, raw sewage, petroleum from shipping accidents, and detergents This makes water unfit for drinking, cooking, cleaning, and other purposes. It may provide an environment suitable for growth of bacteria, algae bloom and other parasites which even destroys the life of animals residing in the water body like fishes.
All other forms of pollution eventually make their way to water and disturb the pH of water. Biochemical Oxygen demand (BOD) is the attribute which measures the pollution in water body at surface level.
Hence,Cyanide, raw sewage, petroleum from shipping accidents, and detergents are all examples of Water pollution.
