What is food chain?

Food chain, in ecology, the sequence of transfers of matter and energy in the form of food from organism to organism. Food chains intertwine locally into a food web because most organisms consume more than one type of animal or plant.

In a food chain a primary consumers eats the producer, a secondary consumer eats the primary consumer and then the tertiary consumer eats the secondary consumer. The level of poison will increase as it goes down the food chain so the tertiary consumer will have the highest amount of toxins in it.
