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. Secondary consumer definition. secondary consumers are organisms that eat primary consumers for energy. primary consumers are always herbivores, or organisms that only eat autotrophic plants. however, secondary consumers can either be carnivores or omnivores. carnivores only eat other animals, and omnivores eat both plant and animal matter.
Food Chains Producer Primary Consumer Secondary Consumer Tertiary The organisms that consume the producers are herbivores: the primary consumers. secondary consumers are usually carnivores that eat the primary consumers. tertiary consumers are carnivores that eat other carnivores. higher level consumers feed on the next lower trophic levels, and so on, up to the organisms at the top of the food chain: the. 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. 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 predator. top predators, also called apex predators, eat other consumers. Higher level consumers include secondary consumers (third trophic level), which are usually carnivores that eat the primary consumers, and tertiary consumers (fourth trophic level), which are carnivores that eat other carnivores. in the lake ontario food chain, shown in figure \(\pageindex{g}\), the chinook salmon is the apex consumer at the.
