Biological magnification

Biological magnification is a process where a substance increases in concentration in organisms and moves farther down the food chain. For an example, a small animal may ingest something that had a toxic substance on it, then a larger animal eats the smaller animal, now the larger animal has some toxic substance too. This cycle continues and the concentration increases as the toxic substance travels up the food chain. As pictured above bug contol or pesticide is one of the most common substances to go through this process.
