Food Chain And Food Webs Explained Here, the producers are consumed by the predators primary and secondary consumers and then the detritivores and finally by decomposers. when many such individual food chains occur in an ecosystem, it is known as food web. a food chain shows a direct transfer of energy between organisms. as every organism can feed on multiple things, a food web. Tertiary consumers often occupy the top trophic level, and so are predated by no other animals; in this case they are called “apex predators”. however, when they die their bodies will be consumed by scavengers and decomposers. sometimes in a food chain there is an apex predator above the tertiary consumer.
Trophic Levels Producer Primary Consumer Secondary Consumer There may be more levels of consumers before a chain finally reaches its top predator. top predators, also called apex predators, eat other consumers. higher level consumers (i.e., secondary, tertiary, and above) can be carnivores (animals that eat other animals) or omnivores (animals that eat both plants and animals). omnivores, like people. Further trophic levels are numbered subsequently according to how far the organism is along the food chain. level 1: plants and algae make their own food and are called producers. level 2: herbivores eat plants and are called primary consumers. level 3: carnivores that eat herbivores are called secondary consumers. Aquatic animal that strains nutrients from water. food chain. noun. group of organisms linked in order of the food they eat, from producers to consumers, and from prey, predators, scavengers, and decomposers. food web. noun. all related food chains in an ecosystem. also called a food cycle. Food chains. a food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another; the levels in the food chain are producers, primary consumers, higher level consumers, and finally decomposers. these levels are used to describe ecosystem structure and dynamics.

Some consumers are in between trophic levels because they eat a combination of primary, secondary, and or tertiary consumers. all the producers and consumers eventually become nourishment for the decomposers (mushrooms, mold, and bacteria) and detritivores (earthworms) in the soil, which are depicted at the bottom of the illustration. Within this broad designation are five main trophic levels: primary producers, primary consumers, secondary consumers, tertiary consumers, and apex predators. decomposers and detritivores .
