Primary consumers: what they are, examples, importance

We explain what primary consumers are, their characteristics and importance. Finally, we give several examples of primary consumers.

What are primary consumers?

The primary consumers They are living beings, mostly herbivores, that feed on autotrophic organisms that are part of the base of the food chain.

Primary consumers are also known as heterotrophs, which means that they cannot make their own food, unlike autotrophic organisms, which are self-sufficient in that sense. For that reason, primary consumers They depend on living things like plants..

In all bioclimatic landscapes there are primary consumers, which feed on plant organisms and algae, thus functioning as a first link between producer organisms and other types of consumer living beings.

Characteristics of primary consumers

HE feed on autotrophic organismswho are autonomous and capable of preparing their own food.
In order to get energy, require ingesting organisms They have energy stored in the form of starch, sugar or cellulose.
Their main livelihood is plants, trees, foliage, stems and other plant componentssuch as flowers or nectar.
They enter the food chain as food source of other types of consumersas is the case with carnivores.
They have a fundamental role in ecosystemsassisting in the transfer of energy and maintaining a balance.
Count on physiological adaptations which allow them to process carbohydrates that are produced by plants through photosynthesis.

Examples of primary consumers

Grasshopper: Almost all species of grasshoppers are herbivorous, so they feed on leaves, flowers, stems, grasses, and seeds.
deer: They feed mainly on grass and can live in different types of habitats.
squirrels: Also present in numerous habitats, squirrels feed on seeds, nuts, shoots, fruits, and flowers.
Horses: They eat mainly grass.
rabbits: They eat fresh vegetables, hay, fruit and pellets.
goats: They eat grasses, grains and hay.
caribou: They live in the tundra and eat plants, flowers, leaves, fungi, shrubs, and lichens.
zooplankton: small organisms that move through aquatic currents and feed on phytoplankton, algae and bacteria.
beavers: Found in ponds, swamps, rivers, and streams. Their diet consists of soft, aquatic plants, bark, roots, and stems.
toucans: They are inhabitants of the tropical forest and their diet is based on the consumption of seeds that come from different plants.
Cows: ruminant animals that feed mainly on herbs and grasses.
caterpillars: Certain species of caterpillars feed on plants and, in turn, serve as food for some birds.
Snails: Its main diet consists of vegetable remains, fruits and even dirt.
butterflies: insects that survive thanks to the nectar they obtain from flowers.
giraffes: ruminant animals that feed mainly on the leaves of acacia, a tall tree.
rhinos: They are classified as megaherbivores, due to their large size. Their diet consists of herbs and shrubs.
protozoa: tiny organisms that feed on bacteria and microscopic algae.
Fish: Some species of fish, such as the golden otter, only eat algae.
turtles: reptiles that base their diet solely on plant sources.
chickens: These birds feed on seeds.
koalas: Mammals whose diet consists mainly of eucalyptus leaves.
hummingbirds: small birds that feed on nectar that they take from flowers.
aphids: they are considered a parasitic species; They take nutrients from the plants where they live.

Differences between primary consumers, secondary consumers and tertiary consumers

Primary, secondary and tertiary consumers are part of the food chain and the presence of each one allows the balance of the ecosystems.

The primary consumers are herbivores and they base their diet on organic matter produced by autotrophic living beings, that is, plants or bacteria that produce their own food.

For their part, the secondary consumers are carnivoresthat is, they feed on the meat of other living beings, so their food source is herbivores or primary consumers.

Finally, the tertiary consumers are also called top predatorssince they feed on other carnivores and have almost no predators that wake them up.
