Eric
energy from the sun is trapped by green plants during photosynthesis, producing
chemical energy9food or carbohydrates
? green plants are producers and occupy the first trophic level
? green plants are eaten by herbivores called primary producers as they occupy the second
trophic level
? herbivores are eaten by carnivores, secondary consumers, which occupy the third trophic
level
? when organisms 9plant and animals) die, fungi and bacteria which are saprophytic
organisms feed on them thus causing them to decompose into simple substances e.g.
mineral salts
? these organisms are called decomposers and detrivores
? decomposer feed on dead organic matter hence cause decomposition and decay which
releases nutrients for plants, linking biotic and a biotic components
? at all levels energy is lost through respiration
