Model Answer
(a) Garbage refers to waste material that is discarded as unwanted or useless. It is classified into two classes:
- Biodegradable waste – substances that can be broken down by microorganisms (e.g., food scraps, leaves).
- Non-biodegradable waste – substances that cannot be broken down naturally (e.g., plastics, glass).
(b) When we say enzymes are specific in their action, it means that each enzyme can catalyse only one particular type of reaction or act on one particular type of substrate. For example, the enzyme that breaks down starch cannot break down proteins.

Explanation
- For (a), the two standard classes are biodegradable and non-biodegradable — always name both with a brief example.
- For (b), "specific" means one enzyme = one substrate/reaction. Examiners expect you to state this clearly and ideally give an example. Note: the source passages do not cover enzymes in detail, so this answer draws on standard CBSE Class 10 Biology content (Chapter 6 – Life Processes). Keep it to one or two lines.
