Question

Name the term used for the materials which cannot be broken down by biological processes. Give two ways by which they harm various components of an ecosystem.

Answer 1

The term used for materials that biological processes cannot break down is non-biodegradable. Two ways in which non-biodegradable materials harm various components of an ecosystem are:

1. Pollution: Non-biodegradable items, like plastic and metals, can remain in the environment for long durations. These pollutants build in ecosystems, contaminating water, soil, and air. Pollution can negatively impact aquatic life and soil creatures, disrupting ecosystem balance.
2. Toxicity: Non-biodegradable materials, including chemicals and heavy metals, can release hazardous substances into the environment. These poisons can harm the ecosystem's health of plants, animals, and humans. Toxins can accumulate in the food chain, providing a risk to higher-level consumers.
