Trophic levels. an organism's position in a food web. it is based on food feeding. decomposers. organisms like fungus, bacteria, and some invertebrates that get energy from all trophic levels! they help cycle nutrients. ecosystem. all of the living and non living things that interact together. trophic level 1.
Trophic Level Producers Primary Secondary Tertiary 3rd trophic level: secondary consumer. consumes primary consumers. snakes eat mice. 4th trophic level: tertiary consumer. consumes secondary consumers. hawks eat snakes. many consumers feed at more than one trophic level. humans, for example, are primary consumers when they eat plants such as vegetables. Examples of trophic levels, all of which will be described below, are primary producers, primary consumers or herbivores, and secondary and higher level consumers, or predators. food webs are based on the productivity of photosynthetic organisms, such as blue green bacteria , algae , and plants. The trophic level of an organism is the position it occupies in a food web. within a food web, a food chain is a succession of organisms that eat other organisms and may, in turn, be eaten themselves. the trophic level of an organism is the number of steps it is from the start of the chain. a food web starts at trophic level 1 with primary. 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.

Ecosystem trophic levels, food chains, interactions: together, the autotrophs and heterotrophs form various trophic (feeding) levels in the ecosystem: the producer level (which is made up of autotrophs), the primary consumer level (which is composed of those organisms that feed on producers), the secondary consumer level (which is composed of those organisms that feed on primary 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.
