Substances said to be biodegradable:
Understanding Biodegradable Substances
Biodegradable substances are materials that can decompose naturally over time. This decomposition is facilitated by living organisms.
Key Definition
The term 'biodegradable' specifically refers to the ability of a substance to be broken down through biological processes. These processes involve microorganisms like bacteria and fungi.
- Option 1 is incorrect: Physical processes (like grinding or dissolving) do not define biodegradability.
- Option 2 is incorrect: Chemical processes (like oxidation or hydrolysis without biological agents) are not the primary definition.
- Option 3 is correct: Biodegradability hinges on breakdown by living organisms or biological agents.
- Option 4 is incorrect: This is the opposite of biodegradable.
Therefore, substances that can be broken down by biological processes are termed biodegradable.
