Nota de escopo:	Secuencia de transferencias de materia y energía de un organismo a otro en forma de ALIMENTOS. Las cadenas alimentarias se entrecruzan localmente y forman una red alimentaria porque la mayoría de los organismos consumen más de un tipo de animal o vegetal. Las PLANTAS, que convierten la ENERGÍA SOLAR en alimento mediante la FOTOSÍNTESIS, son la fuente principal de alimentos. En una cadena de predadores, un animal que se alimenta de vegetales es devorado por un animal mayor. En una cadena de parásitos, un organismo más pequeño consume parte de un huésped mayor y a su vez puede ser parasitado por organismos más pequeños. En una cadena de saprófitos, los microorganismos viven de materia orgánica muerta.

Nota de escopo:

The sequence of transfers of matter and energy from organism to organism in the form of FOOD. Food chains intertwine locally into a food web because most organisms consume more than one type of animal or plant. PLANTS, which convert SOLAR ENERGY to food by PHOTOSYNTHESIS, are the primary food source. In a predator chain, a plant-eating animal is eaten by a larger animal. In a parasite chain, a smaller organism consumes part of a larger host and may itself be parasitized by smaller organisms. In a saprophytic chain, microorganisms live on dead organic matter.
