What us biological magnification?
Answers
Biological magnification refers to the increase in the concentration in certain toxicants at each trophic level.
E.g= Chemical like pesticides, insecticides etc are used to protect crops. these chemicals are washed away with water into the soil, water bodies like ponds and rivers. these chemicals are absorbed by the plants along with water minerals and from water by aquatic plants and animals. These chemical accumulate in the body tissues at each trophic level resulting in high concentration in the tissues of higher consumer. This phenomena is known as biological magnification.
Biological magnification - unknowingly sometimes harmful chemicals enters our body through through the food chain which are non biodegradable and gets accumulated in the body since humans occupy the toppest or highest trophic level in any food chain therefore harmful Chemicals mostly get concentrated in humans as we go up in the food chain this is what is called as Biological magnification
Food chain- sequence of organisms taking part in various biotic levels
E.g. grass - grasshopper -frog-snake-eagle
