Primary Consumer Definition. A primary consumer is an organism that feeds on primary producers. Organisms of this type make up the second trophic level and are consumed or predated by secondary consumers, tertiary consumers or apex predators.
Secondary consumers can be sorted into two groups: carnivores and omnivores. Carnivores only eat meat, or other animals. Some secondary consumers are large predators, but even the smaller ones often eat herbivores bigger than they are in order to get enough energy. Spiders, snakes, and seals are all examples of carnivorous secondary consumers.
Secondary consumers occupy the third trophic level in a typical food chain. They are organisms that feed on primary consumers for nutrients and energy. Every secondary consumer, whether a herbivore or carnivore, must have primary consumers in its diet to survive.
"Consumer" and "producer," in this usage, refer to the production and consumption of energy in a form that can be used for life processes. Ecologists talk of consumers and producers when discussing food webs in a particular place. Possible examples of primary consumers differ based on the specific biome being discussed.
Secondary and higher consumers may eat primary consumers as well as plants or lower-level consumers. A food chain has at least three elements: a producer, a primary consumer and a secondary consumer. An example of a marine food chain is algae as producer plants, small crustaceans as primary consumers and whales as secondary consumers.
These are called autotrophs or primary producers. Next come organisms that eat the autotrophs; these organisms are called herbivores or primary consumers-- an example is a rabbit that eats grass. The next link in the chain is animals that eat herbivores - these are called secondary consumers-- an example is a snake that eat rabbits.
Learn all about secondary consumers and their place in the food pyramid. We will look at examples of secondary consumers. There is a short quiz to follow that you can take to test your knowledge ...
Tertiary consumers can be carnivores or omnivores. Their diet can comprise only meat or include plants as well. A hawk, for example, can feed on primary consumers such as birds, as well as secondary consumers such as snakes.. Let’s look at some other examples before we explore the functions of tertiary consumers.
The hierarchical pyramid of energy flow in any ecosystem goes like this: Sun -> Primary Producers -> Primary Consumers -> Secondary Consumers -> Tertiary Consumers Primary consumers, which is more or less synonymous with "herbivores," eat the thin...
In a food chain, primary consumers are assigned the task of converting plant nutrients into digestible form for secondary and tertiary consumers. Examples of primary consumers include all the plant-eating species (herbivores) found on the planet, right from leaf-cutter ants to elephants.
