- Consumers - National Geographic Society
For example, a grasshopper living in the Everglades is a primary consumer Some other examples of primary consumers are white-tailed deer that forage on prairie grasses, and zooplankton that eat microscopic algae in the water

Photograph Secondary Consumers A fish, caught by a heron in the U S city of Nokomis, Florida, has another fish in its mouth These secondary consumers in the food chain prey on other organisms Producers, such as plants, create their own nutrients, while primary consumers, also called herbivores, rely on producers for food Photograph by Ernie Aranyosi, MyShot
- Energy Transfer in Ecosystems - Education
At each level, some of the biomass consumed is excreted as waste, some energy is changed to heat (and therefore unavailable for consumption) during respiration, and some plants and animals die without being eaten (meaning their biomass is not passed on to the next consumer)
- Food Chains and Webs - Education
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
- Food Web - Education
In a desert ecosystem, a mouse that eats seeds and fruits is a primary consumer In an ocean ecosystem, many types of fish and turtles are herbivores that eat algae and seagrass

Another kind of secondary consumer is an omnivore, which is an animal that feeds on both plants and other animals Any animal that hunts and feeds on other animals is called a predator, and the animals that predators feed on are called prey
- Whos in My Backyard? - Education
Make sure to include terms that describe an organism by what it feeds on (herbivore, carnivore, and omnivore) and the trophic levels (primary producer, primary consumer, secondary consumer, tertiary consumer, and decomposer)
- Herbivores - National Geographic Society
An herbivore is an animal that mainly eats plants Herbivores vary in size from small, like bugs, to large, like giraffes An animal’s diet determines where it falls on the food chain, a sequence of organisms that provide energy and nutrients for other organisms Each food chain consists of several trophic levels, which describe an organism’s role in energy transfer in an ecosystem
