An organism that eats producers or other organisms for energy is called a consumer. The three main types of consumers are herbivores, carnivores and omnivores.Continue Reading
In an ecosystem, primary producers are the plants and other organisms that are able to make their own food. Herbivores eat primary producers, so they are known as plant-eating organisms. Deer and cows are examples of herbivores.
Carnivores, also called secondary consumers, eat herbivores and other carnivores. Lions are classified as carnivores because they feed on other animals. Omnivores eat plants and animals. The raccoon is a good example of an omnivore because it eats vegetables as well as fish and mice.Learn more about Zoology
A biomass pyramid is a graphic illustration of the mass of organisms at each trophic level, which tends to get less as it goes up from producers to each level of consumer. There are inversions, however, where the mass of consumers is greater than the mass of producers.Full Answer >
Various protist species are important to humans because they are the primary producers at the base of the food pyramid, turning the energy from the sun into a form that can be passed from organism to organism up the food pyramid. Protists also stabilize the ion levels of water, which allows seaweed and fish, both of which are important food sources for humans, to thrive.Full Answer >
An organism that eats other organisms, living or dead, is called a consumer. Consumers are known by other names, depending on the type of food consumed. Categories of consumers include the omnivores, the meat-eating carnivores, the fruit-eating frugivores, the plant-eating herbivores and the detrivores that eat dead organic material.Full Answer >
In the trophic structure, classification of organisms in an ecosystem occurs through the energy source and consumption of food by an organism. The trophic structure represents the relationship between species and food sources.Full Answer >
