Solution

The term “Bio-magnification” refers to the increase in the concentration of non-degradable pollutants as they pass through the food chain.

Here's a step-by-step explanation:

  1. Non-degradable pollutants are substances that cannot be broken down naturally in the environment. They include things like heavy metals and certain types of plastic.

  2. These pollutants can enter the food chain when they are ingested by small organisms. For example, a small fish might ingest a pollutant when it eats plankton.

  3. When a larger organism eats the small fish, it also ingests the pollutant. Because the larger organism eats many small fish, it ends up with a higher concentration of the pollutant in its body.

  4. This process continues up the food chain, with each level having a higher concentration of the pollutant. This is what is meant by "bio-magnification".

So, the correct answer is d. Increase in the concentration of non-degradable pollutants as they pass through the food chain.
