How To Define A Food Chain. It begins with producer organism follows the chain and ends with decomposer organism. In scientific terms a food chain is a chronological pathway or an order that shows the flow of energy from one organism to the other.
An example of food chain is a fly being eaten by a frog and then the frog is eaten by a larger animal. The definition of a food chain is a system where a small animal is the food for a larger animal which in turn is the food for an even larger animal. The food chain is a linear sequence of organisms where nutrients and energy is transferred from one organism to the other.
It starts with the primary source like the sun or hydrothermal vents where producers make food continues with consumers or animals who eat the food and ends with the top predator.
The definition of a food chain is a system where a small animal is the food for a larger animal which in turn is the food for an even larger animal. But it flows from one level to the other through different organisms. For example you could write the food chain for a lion like this. In other words it is the chronological order of who eats whom in a biological community.
