Understanding the definition of biodegradable substances is crucial.
Biodegradable Definition Breakdown
The term "biodegradable" combines two parts:
- Bio-: Refers to life or biological processes.
- Degradable: Means capable of being decomposed or broken down.
Therefore, biodegradable substances are materials that can be broken down naturally by living organisms, such as bacteria and fungi.
Evaluating the Options
Let's examine the provided options based on this definition:
- Option 1: Substances that are broken by biological process - This aligns perfectly with the meaning of biodegradable.
- Option 2: Substances that are broken by chemical process - This describes chemical degradation, not necessarily biodegradation.
- Option 3: Substances that are broken by mechanical process - This refers to physical breakdown (like shredding), not biological decomposition.
- Option 4: Substances that are broken by physical process - Similar to mechanical breakdown, this involves physical changes, not biological action.
Conclusion on Biodegradability
The correct definition hinges on the involvement of biological agents. Option 1 accurately describes this process.
