Question

What are biodegradable and non-biodegradable wastes? Give two examples of each.

Hint:

Biodegradable wastes are easily decomposed by natural processes, while non-biodegradable wastes persist in the environment, contributing to pollution.

Answer 1

Step 1: Define Biodegradable Wastes.
Biodegradable wastes are organic materials that can be broken down by microorganisms such as bacteria and fungi into simpler substances, thus returning to the environment without causing pollution. Step 2: Examples of Biodegradable Wastes.
1. Food Waste: Organic food scraps, such as vegetable peels, fruits, and leftovers, can be decomposed by bacteria and fungi.
2. Wood: Wood, when exposed to microorganisms, decomposes over time, making it biodegradable. Step 3: Define Non-Biodegradable Wastes.
Non-biodegradable wastes are materials that cannot be broken down by natural processes or microorganisms. These wastes persist in the environment, causing pollution and environmental damage. Step 4: Examples of Non-Biodegradable Wastes.
1. Plastic: Plastics do not decompose naturally and can remain in the environment for hundreds of years.
2. Metal Cans: Metal cans, such as those used for food or beverages, are non-biodegradable and can take a long time to decompose.
