A food web is all of the food chains in an ecosystem. The food chain can be defined as. That is they can form one of the links in a food chain.

The arrows used to link each organism to the next represent the direction of energy flow. The feeding level is known as the trophic level.

These detritivores are later eaten by. A sequence usually shown as a diagram of feeding relationships between organisms showing who eats what and the movement of energy through trophic levels.

Each organism in an ecosystem occupies a specific trophic level or position in the food chain or web. For example if you had a hamburger for lunch you might be part of a food chain. Energy is not created or destroyed.
