Question

Bio-degradable wastes can usually be converted into useful substances with the help of:

• A. Bacteria
• B. Nuclear Proteins
• C. Radioactive substances
• D. Viruses

Hint:

Biodegradable waste is primarily decomposed by microorganisms such as bacteria, which recycle nutrients in the ecosystem.

Answer 1

The Correct Option is A

Biodegradable wastes refer to materials that can be broken down naturally by biological organisms. The process through which these materials are decomposed is essential for recycling nutrients back into the ecosystem. Various organisms contribute to this decomposition process, but one group stands out as particularly efficient: bacteria. Here's a breakdown of the reasoning:

1. Bacteria: These are microorganisms that play a crucial role in breaking down organic matter. They produce enzymes that facilitate the decomposition of complex substances in biodegradable waste into simpler compounds.
2. Nuclear Proteins: These are proteins associated with the cell nucleus and are not related to waste decomposition. They do not participate in the degradation of organic matter.
3. Radioactive Substances: These are elements that emit radiation as they decay. They are not involved in biodegradation and can actually harm biological processes.
4. Viruses: While they can affect living organisms, viruses do not contribute to the breakdown of biodegradable materials.

Given this analysis, bacteria are the correct and most effective agents for converting biodegradable waste into useful substances. Their natural ability to break down organic matter supports environmental sustainability and nutrient cycling.
