Once used, energy is unavailable for reuse Food chain follows flow of energy in ecosystem Sun = Producer = primary consumer = secondary consumer = tertiary consumer = decomposer Producers trap energy in photosynthesis (plants) Herbivores eat plants, as do omnivores getting chemical energy and building blocks for other molecules Carnivores and omnivores eat the herbivores, getting energy from herbivore molecules Decomposers break down organic molecules in remains at all levels Food web is more accurate, because there are range of food sources and complex, interconnected chains Trophic level is each level in a food web First is primary producers Second trophic level is primary consumers, etc. Energy moves from one trophic level to next as long as it isn t used for biological work Pyramid of numbers shows number of organisms at each trophic level.
