Nutrition Pyramid

Question: explain why information such as DDT affects the organisms, which are highest in nutrition pyramid? not informations but poisons like DDt

Answer: First, DDT is not information it is a chemical toxin. Second, it becomes more of a problem higher in the food chain because it becomes more concentrated as it moves up the food chain. Think of the problem like this: lots of animals low on the chain eat tiny amounts of the toxin each, but the next animal needs to eat lots of the lower animals thus ingesting lots of the toxin, and the next animal in the chain eats lots of those and so on.
