Food Chains And Food Webs Examples Of Food Chains And Food Webs 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. A food chain is a network of links in a food web. 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.
Food Chain And Food Webs Explained Secondary consumers can be defined as a group of living organisms that mainly feed on primary consumers or herbivores to get energy. they are placed on the third trophic level in a food chain. some secondary consumers also feed on both producers and primary consumers. so, secondary consumers range from carnivores that consume meat to omnivores. A food web is a graphic representation of a holistic, nonlinear web of primary producers, primary consumers, and higher level consumers used to describe ecosystem structure and dynamics (figure 1). figure 1. example of simplified food chains (a) and food webs (b) of terrestrial and marine ecosystems. A million to one marine food webs are usually longer than terrestrial food webs. scientists estimate that if there are a million producers (algae, phytoplankton, and sea grass) in a food web, there may only be 10,000 herbivores. such a food web may support 100 secondary consumers, such as tuna. Primary consumers; secondary consumers; tertiary and other high level consumers; in both food webs and food chains, arrows point from an organism that is consumed to the organism that consumes it. in many ecosystems, the bottom of the food chain consists of photosynthetic organisms, such as plants or phytoplankton, known as primary producers.

A food chain outlines who eats whom. a food web is all of the food chains in an ecosystem. each organism in an ecosystem occupies a specific trophic level or position in the food chain or web. producers, who make their own food using photosynthesis or chemosynthesis, make up the bottom of the trophic pyramid. primary consumers, mostly herbivores, exist at the next level, and secondary and. The second consumers (trophic level 3) in the desert food web include birds and scorpions, and tertiary consumers making up the fourth trophic level include bird predators and foxes.
