A product is biodegradable if it can be consumed or eaten by an organism such as an animal, insects, bacteria, or fungus so that it is broken up into simpler more basic products. The resulting products can then be used by other plants or animals as a source of nourishment starting the process over again.
In other words, biodegradable items left on the ground or garbage dumps are eaten by animals or insects and excreted as simpler wastes which are processed by bacteria in the ground leaving leaving simpler biological products that help make fertile soil from which plants grow that feed animals which die or are used to make other biodegradable items, continuing the cycle.
Although some metals are needed to sustain life, they are used in very small amounts. Metals such as cans, scrap metal, and other parts left on the ground just stay there. Some of it exposed to the elements can rust (meaning it combines with oxygen) or react chemically with other products. In general they are not part of the life sustaining biological cycle.
No.
non- biodegradeable pollutants - which do not degrade by microbes or degrade very slowly. [eg. plastics, glass, heavy metal compounds, pesticides, etc] biodegradeable polutants - which can be decomposed by micro-organisms [their accumulation which may not degrade completey, causes pollution eg. sewage]
yes
It is a lot!
They are not biodegradeable.
If it is biodegradeable, then it just becomes "part" of the land. If it is not biodegradeable, it justs sits there.
Plastic bottles are not biodegradable.
cats and dogs
this depends on the type of polymer
biodegradable and non-biodegradeable
Biodegradeable.
Yes they are
no lycra is not biodegradable as it is man made
