Difference between biotic & abiotic degradation

 Difference between biotic & abiotic degradation

Aboitic decomposition means degradation of a substance or material through chemical or physical means like the changes that occur during hydrolysis.

The biotic decomposition means the metabolic breakdown of materials or substances into simpler components by living organisms generally through the actions of microorganism. Animal decomposition starts at the moment of death, as a result of two factors:

  1. Autolysis-This is the breaking down of tissues by the body’s own interior chemicals and enzymes, and
  2. Putrefaction- This is the breakdown of tissues by bacteria. These processes discharge gases that are the principal source of the unmistakably putrid odor of decaying animal tissue.

The main decomposers are bacteria or fungi, although larger scavengers as well play a significant role in decomposition if the body is available to insects, mites and other animals.

The main significant arthropods that are mixed up in the process consist of carrion beetles, mites, the flesh-flies (Sarcophagidae) and blow-flies (Calliphoridae), like the green-bottle fly seen in the summer.

The major crucial non-insect animals that are naturally involved in the process comprise mammal and bird scavengers, like coyotes, dogs, wolves, foxes, rats, crows and vultures.

A few of these scavengers as well eliminate and scatter bones, which they swallow at a later time. Aquatic and marine environments have break-down agents that comprise bacteria, fish, crustaceans, worms and a massive amount of carrion scavengers.

Decomposers form a significant part of our ecosystem. They are in fact minute micro-organisms that assist in the maintenance of the ecological balance in our environment. When any living organism dies ,the blood circulation ceases and the body turns static, decomposers begin to alter the matter from complex to simpler substances.

The decomposers work on dead matter and transform them into simpler form leaving behind the manure which makes the soil fertile and makes available suitable conditions for the plants to grow. Owing to this, the ecological cycle continues moving from something like

Plants – Herbivores – Carnivores – Die and Decomposed by Decomposers – Soil – Plants. Decomposers can readily decompose biodegradable substances but can as well decompose non-biodegradable substances. It’s just metals, and the like that take thousands of years to get decomposed.

The amount of energy available at each trophic level lessens as it moves through an ecosystem. As small as 10 percent of the energy at every trophic level is transferred to the subsequent level; the remaining is lost mainly through metabolic processes like heat.
