Food chains have at least three members: the producer, the primary consumer, and the secondary consumer. In a simple food chain, the primary producer is a plant, the primary consumer is a herbivore that eats the plant and the secondary consumer is a carnivore that eats the primary producer.
What is a Primary Consumer?
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.
Primary consumers make up the second trophic level. They are also called herbivores. They eat primary producers—plants or algae—and nothing else.
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.
Examples of primary consumers can include rabbits, bears, giraffes, flies, humans, horses, and cows.
Primary Consumer Diagram
An organism that feeds on the primary producers is described as a primary consumer. Secondary consumers, tertiary consumers, and apex predators ingest or predate organisms of this sort, which make up the second trophic level. Herbivores which feed on the autotrophic plants that produce their own food via photosynthesis are the most common primary consumers.
Herbivores have rows of wide, flat teeth that are used to rasp, grind, and tear tough plant material and woody stems; primary consumers often have specific physiological adaptations which allow them to process carbohydrates which are produced through photosynthesis, which can be difficult to break down and extract nutrition from.

Some primary consumers examples
Rabbits
A rabbit is a small mammal that is a primary consumer. They are herbivores and eat mostly vegetation. In the wild, rabbits live in burrows and are very active at night.
Beavers
Beavers live in lakes, ponds, marshes, rivers, and streams. They are known for building watertight dams from sticks, branches, reeds, mud, and saplings. These dams contribute to the ecosystem they live in by preventing stream erosion.
The main diet of beavers consists of soft plants, bark, stems, and roots of water plants. On top of being hunted by humans for their fur and meat, beavers have to watch out for predators such as bears, coyotes, foxes, and lynxes.
Caribou
A caribou is a large mammal that is a primary consumer. They are herbivores and eat mostly vegetation. Caribou are also known as reindeer. In the wild, they live in herds and migrate long distances every year.
Horses
A horse is a mammal that is a primary consumer. They are herbivores and eat mostly vegetation. Horses are very social animals and live in herds. In the wild, they roam freely and graze on grasses all day long.
Zebra
Zebras eat mostly grass but will also consume leaves and stems from bushes. They have strong front teeth to clip off the tips of grass and spend many hours grazing each day. You can mostly find them in savanna habitats, where they have to be careful of lions and cheetahs.
The stripes on zebras help them camouflage to confuse predators. These stripes are also unique on every animal, similar to fingerprints.
Cows
A cow is a mammal that is a primary consumer. They are herbivores and eat mostly vegetation. Cows are very social animals and live in herds. They are domesticated and used for milk and meat production.
Goats
A goat is a mammal that is a primary consumer. They are herbivores and eat mostly vegetation. Goats are very social animals and live in herds. They are domesticated and used for milk, meat, and fiber production. A baby goat is called a kid.
Wildebeest
A wildebeest, or Gnu, is a mammal that is a primary consumer. They are herbivores and eat mostly vegetation. Wildebeests live in herds and migrate long distances every year.
Butterflies
Butterflies can be found worldwide in different ecosystems, except for the Arctic. They have a straw-like mouthpart called a proboscis that restricts them to liquid diets. Their main food source is nectar from flowers.
Some butterflies live in the desert and eat nectar from cactus flowers. Secondary consumers in the desert, such as lizards, eat these primary consumers.
Grasshoppers
Most grasshoppers are herbivores and eat leaves, flowers, stems, grass, and seeds. You can typically find these primary consumers in grassland biomes. Their top predators are mice, spiders, birds, and lizards.
The few grasshopper species that sometimes scavenge for dead insects as extra protein are not considered primary consumers. These include praying mantis and desert locusts.
Capybara
A capybara is a rodent that is a primary consumer. They are herbivores and eat mostly vegetation. Capybaras are the largest rodents in the world and live in social groups.
Red Squirrel
A red squirrel is a small mammal that is a primary consumer. They are herbivores and eat mostly vegetation. Red squirrels are very active and live in trees.
Camels
A camel is a mammal that is a primary consumer. They are herbivores and eat mostly vegetation. Camels are adapted to living in desert conditions with long eyelashes and two rows of eyelashes to protect their eyes from the sand.
