Explanation:
A food chain shows how each living thing gets food, and how nutrients and energy are passed from creature to creature. Food chains begin with plant-life, and end with animal-life. Some animals eat plants, some animals eat other animals. A simple food chain could start with grass, which is eaten by rabbits.
Grass → Grasshopper → frog → snake → peacock
Grass — Producer — trophic level.
Grasshopper — I Consumer
(Herbivores) — II trophic level’.
Frog — II Consumer
(Carnivores) — II trophic level
Snake — III Consumer
(Carnivores) — III trophic level
Peacock — IV Consumer
(Carnivores) — V trophic level.
The pollutants are absorbed by plant from the soil and enter the food chain. Being non-biodegradable they accumulate progressively at, each trophic level. As human occupy the top level of any food chain, the maximum concentration of chemicals is found in our bodies.
This phenomenon is called biological magnification.
