Question

definition of food chain

Answer 1

food chains are the directional paths of energy, which start with producers and end with decomposers. For example plants get energy from sunlight, and they produce there own food, so they are known as producers, and these plants are eaten by animals , known as herbivores, e.g; dear goat. These herbivores are also killed and eaten by carnivores, as they are totally dependent on flesh or meat. Decomposers are the last to stop the food chain, they eat the things no one else wants to.

Answer 2

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), detritivores (like earthworms or woodlice), or decomposer species (such as fungi or bacteria). A food chain also shows how the organisms are related with each other by the food they eat. Each level of a food chain represents a different trophic level.
