Question

but is the reason that some substance are biodegradable and some non-biodegradable

Answer 1

Hey....mate:)

Here is ur answer.......

________________________________________________________________

Substances that are broken down by biological processes are said to be biodegradable. In our environment, many of the substances are broken easily by decomposers (bacteria and fungi) as they possess specific enzymes for such activity. However, there are other substances also which are not broken down in this manner and are known as non-biodegradable substances. Since these substances are not degraded by bacteria and fungi, so they persist for a long time.

Answer 2

♤ Substances which are organic are biodegradable.Exmaple :- Agricultural waste

♤ Substances which are inorganic are non bio degradable. Example :- Polythene bags

♤ Decomposers can utilise organic substances as their food while other substances cannot be utilised by Decomposers as food .

♤ Due to this reasons some substances are biodegradable while other are non bio degradable.
