There are two types of food chains: the grazing food chain, beginning with autotrophs , and the detrital food chain, beginning with dead organic matter. In a grazing food chain, energy and nutrients move from plants to the grazing herbivores consuming them, and to the carnivores or omnivores preying upon the herbivores. In a detrital food chain, dead organic matter of plants and animals is broken down by decomposers, e.g., bacteria and fungi, and moves to detritivores and then carnivores.
