Trophic Levels Producer Primary Consumer Secondary Consumer

Trophic Level Definition Examples Facts Britannica Definition: trophic level. a species’ trophic level is their position in the food chain or web. at the bottom of the food web are autotrophs, also known as producers. the next level is herbivores (primary consumers), these species feed on producers for their energy source. herbivores are consumed by omnivores or carnivores. The second trophic level consists of herbivores, these organisms gain energy by eating primary producers and are called primary consumers. trophic levels three, four and five consist of carnivores and omnivores. carnivores are animals that survive only by eating other animals, whereas omnivores eat animals and plant material.

Trophic Level Definition Examples And Diagram 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. 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. 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. The second trophic level consists of organisms that eat the producers. these are called primary consumers, or herbivores. deer, turtles, and many types of birds are herbivores. secondary consumers eat the herbivores. tertiary consumers eat the secondary consumers. there may be more levels of consumers before a chain finally reaches its top.
