Question

Which of the following facilitates decomposition of organic waste by bacterial action?

Select one:
A. Incinerator
B. Panel
C. Biogas digester
D. Plastic bag

Answer 1

Explanation:

Organic matter is the food for many small animals in the water and sediment, and organic matter is decomposed by bacteria and fungi. A small portion of the organic matter is transformed into the bodies of the small animals, bacteria and fungi, but most of it is oxidized to inorganic compounds – mainly carbon dioxide and ammonia. Of the organic matter consumed by the culture animals and not expelled as feces, most is oxidized for energy with the release of carbon dioxide, ammonia and other inorganic substances. The remainder makes up the biomass of the culture animals.
