A food chain is a linear network of links in a food web starting from producer organisms (such as grass or trees which use radiation from the sun to make their food) and ending at apex predator species (like grizzly bears or killer whales), detrivores (like earthworms or woodlice).

Pictures. For example, grass produces its own food from sunlight. A food chain should begin with a producer because all the components of chain are consumers.

Food chains show how energy is passed from the sun to producers, from producers to consumers, and from consumers to decomposers. How could you add decomposers to the food chain? Trophic levels and efficiency of energy transfer.
The first organism in a food chain is a producer.
For example, grass produces its own food from sunlight. Food chains are a simple model and only show one pathway of energy and material transfer. Food chain follows a single path whereas food web follows multiple paths. A food chain is a flow of energy from a green plant (producer) to an animal (consumer) and to another animal (another consumer) and so on.
