Substances that are not broken down by biological processes are said to be biodegradable .

Substances that are broken down by biological processes are said to be biodegradable. This is due to

Some substances cannot be broken down in nature. What are they called?

___ cannot be broken down into simpler substances.

Enzymes are specific in their action, specific enzymes are needed for the break-down of a particular substance. That is why we will not get any energy if we try to eat coal! Because of this, many human-made materials like plastics will not be broken down by the action of bacteria or other saprophytes. These materials will be acted upon by physical processes like heat and pressure, but under the ambient conditions found in our environment, these persist for a long time. Substances that are broken down by biological processes are said to be biodegradable. Substances that are not broken down in this manner are said to be non-biodegradable. These substances may be inert and simply persist in the environment for a long time or may harm the various members of the eco-system. Why are enzymes specific in their action ?

Any substance that can be burnt to produce energy is called a/an___________.
