[主題詞] Food Chain
[英文釋義] 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.
