Why are carnivores classified as 3rd level consumers?
Flexi Says: A tertiary consumer is an animal that obtains its nutrition by eating primary consumers and secondary consumers. Usually, tertiary consumers are carnivorous predators, although they may also be omnivores, which are animals that feed on both meat and plant material.
Food Chains and Webs
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 tertiary consumers, omnivores and carnivores, follow.
Tertiary consumers, which are sometimes also known as apex predators, are hypercarnivorous or omnivorous animals usually at the top of food chains, capable of feeding on both secondary consumers and primary consumers.
At the third level, primary carnivores, or meat eaters, eat the herbivores; and at the fourth level, secondary carnivores eat the primary carnivores.
Lastly, a hawk (top carnivore) swoops in and eats the snake to derive his energy for survival, which makes the hawk a third order consumer.
Centipedes are flattened, segmented worms with 15 or more pairs of legs–one pair per segment. They hatch from eggs laid during the warm months and gradually grow to their adult size. Centipedes are third-level consumers, feeding only on living animals, especially insects and spiders.
The organisms that eat the primary consumers are meat eaters (carnivores) and are called the secondary consumers.
The carnivorous animals are secondary consumers because: They feed upon the primary consumers or herbivorous animals. Herbivorous animals eat plants so they consume the energy directly from the producers. But carnivores get energy indirectly through the herbivores.
Examples of Carnivorous Animals
Carnivorous mammals include tigers, lions, cheetahs, etc. Black eagles, kites, and hawks are carnivorous birds.
Carnivores are also known as primary consumers.
What animals are 3rd level consumers?
Third-level consumers are any organisms big enough to obtain energy by feeding off lower-level consumers. These are also called tertiary consumers. For example, in a forest ecosystem, snakes eat toads. Heron and large fish, such as bass and walleye, consume smaller fish, frogs and crayfish.
Higher-Level Consumers
Secondary or second-level consumers eat primary consumers. Tertiary or third-level consumers eat lower-level consumers and are sometimes called final consumers. Some secondary and tertiary consumers eat plants as well as lower level consumers, making them omnivores.
| Trophic Level | Where It Gets Food |
|---|---|
| 1st Trophic Level: Producer | Makes its own food |
| 2nd Trophic Level: Primary Consumer | Consumes producers |
| 3rd Trophic Level: Secondary Consumer | Consumes primary consumers |
| 4th Trophic Level: Tertiary Consumer | Consumes secondary consumers |
carnivore, any member of the mammalian order Carnivora (literally, “flesh devourers” in Latin), comprising more than 270 species. In a more general sense, a carnivore is any animal (or plant; see carnivorous plant) that eats other animals, as opposed to a herbivore, which eats plants.
There are three different categories of carnivores based on the level of meat consumption: hypercarnivores, mesocarnivores and hypocarnivores. Carnivores that eat mostly meat are called hypercarnivores.
Definition: Carnivores are types of consumers that consume other consumers only or flesh or meat. Thus, they obtain energy from consumers only. Primary carnivores consume herbivores (primary consumers) and secondary carnivores consume the primary carnivores (secondary consumers).
Tertiary consumers are ones that are on the fourth trophic level. Some examples of tertiary consumers are sea turtles, sea lions, hawks, and foxes.
Carnivores
At the top of the food chain, predators prey on herbivores or other predators. While carnivores only eat meat, omnivores eat both meat and plants. Foxes, wolves, lions, and sharks are types of carnivores. And humans, bears, pigs, and pandas are examples of omnivores.
Tertiary consumers are carnivorous organisms. They feed on other carnivores or herbivores. Lions, tigers, wolves, and foxes are carnivores. They have powerful paws with sharp claws that help them catch prey.
Tertiary consumers are those that eats the secondary consumers (large predators). For example, owls that eat snakes.
What are some 3rd level consumers in the ocean?
Tertiary consumers in the ocean are the larger organisms that feed upon the smaller, secondary consumers. Examples include ringed seals that feed on cod and clown fish that feed on krill. Great white sharks are another type of tertiary consumer, feeding on smaller fish like tuna.
These animals are called consumers because they consume something else to get their food. There are different types of consumers. An animal that eats producers, like plants or algae, is called an herbivore. Carnivores eat other consumers.
SECONDARY CONSUMERS: These are carnivores and feed on primary consumers and producers. For example, dogs, cats, birds etc. TERTIARY CONSUMERS: These are top carnivores that feed on primary and secondary consumers and producers. For example, lion, vulture etc.
Carnivores and omnivores are secondary consumers. Many carnivores eat herbivores. Some eat omnivores, and some eat other carnivores. Carnivores that consume other carnivores are called tertiary consumers.
Carnivores eat other animals. Hence, they depend indirectly upon plants for nutrition and are known as secondary consumers.
Secondary Consumer - Animals that eat primary consumers (herbivores). Tertiary Consumer - Animals that eat secondary consumers ie carnivores that feed on other carnivores. Scavenger - a consumer that eats dead animals (e.g. crab, crow, vulture, buzzard and hyena. )
Large carnivores include wolves and mountain lions. A large carnivore might hunt down large herbivores such as elk and deer. Medium-sized carnivores include hawks and snakes, and these animals typically feed on rodents, birds, eggs, frogs, and insects. Examples of small carnivores include some smaller birds and toads.
Carnivores are those animals that consume only the meat of other animals. Herbivores include those animals that depend on plants or plant products for their food and nutrition.

| Herbivore | Carnivore | Omnivore |
|---|---|---|
| Herbivorous animals feed on plants. | Carnivorous animals eat the flesh of other animals. | An omnivorous animal can eat both plants and also other animals. |
Primary consumers are herbivorous animals that survive off eating plant material. Secondary consumers are those that eat primary consumers, so they must be omnivorous or carnivorous.
Is human a carnivore?
Although many humans choose to eat both plants and meat, earning us the dubious title of “omnivore,” we're anatomically herbivorous. The good news is that if you want to eat like our ancestors, you still can: Nuts, vegetables, fruit, and legumes are the basis of a healthy vegan lifestyle.
These are: Primary consumers (herbivores) - plant eaters (e.g. a cow). Secondary consumers (carnivores) - meat eaters (e.g. a lion) and omnivores. Tertiary consumers (omnivores) - plant and animal eaters (e.g. humans or birds).
Human beings are also considered tertiary consumers. Human is omnivorous which means that they consume both plants and animals. They have a varied diet that consists of organisms from all trophic levels, including decomposers like mushrooms. In marine ecosystems, the larger fish are the tertiary consumers.
The carnivores are broken into tiers; the first level carnivores consist of crustaceans, small fish, jellyfish, and others that generally consume small herbivores. For the second level, third level, and top carnivores, each level consumes more energy than the last.
So the herbivorous animals are the first order consumers. First order consumers depend directly on green plants for food. Herbivorous animals like elephant, camel, cow, buffalo, deer, sheep, goat, rabbit etc. are the first order consumers.
Consumers may be identified by their position in a chain: first order (primary) consumers eat producers; second order (secondary) consumers eat primary consumers; third order (tertiary) consumers eat secondary, and so on along a chain.
There are four types of consumers: omnivores, carnivores, herbivores and decomposers. Herbivores are living things that only eat plants to get the food and energy they need. Animals like whales, elephants, cows, pigs, rabbits, and horses are herbivores. Carnivores are living things that only eat meat.
Examples of carnivores include land mammals such as the tiger, lion, wolf, wolverine and African wild dog; marine mammals such as seals and the orca; birds such as eagles, owls and shrikes; reptiles such as snakes and crocodiles; and ocean animals such as sharks and squid.
Animals that eat only plants are called herbivores (or primary consumers). Animals that eat other animals are called carnivores. Carnivores that eat herbivores are called secondary consumers, and carnivores that eat other carnivores are called tertiary consumers.

Which is high level carnivores?
Top carnivores are the carnivores occupying the top level of a food chain or a number pyramid. They feed on other organisms but aren't fed upon by any predator or so. Eg. Lion.
There are three consumers in the food chain: primary, secondary, and tertiary. Herbivores are considered primary consumers, while carnivores are secondary. Tertiary consumers can be both carnivores and omnivores and receive nutrition from all lower consumers.
Carnivores are the organisms which feed upon other animals for their nutrient intake. They can be also called secondary consumers as they eat other animals. Herbivores are called primary consumers.
In a food chain green plants i.e., producers occupy the first trophic level (T1). Herbivores occupy the second trophic level (T2). Carnivores on the other hand, occupy the third trophic level (T3). Higher level carnivores occupy the fourth trophic level (T4).
These are carnivore-eating carnivores, like eagles or big fish. Some food chains have additional levels, such as quaternary consumers (carnivores that eat tertiary consumers). Organisms at the very top of a food chain are called the apex consumers.
a. Carnivores occupy the third trophic level in the food chain because the second level is occupied by herbivores. Herbivores are organisms who feed on plants.
Tertiary consumers are those that eats the secondary consumers (large predators). For example, owls that eat snakes.
Primary consumers are always herbivores, or organisms that only eat autotrophic plants. However, secondary consumers can either be carnivores or omnivores.
Carnivores that have no natural predators are known as apex predators; they occupy the top of the food chain. Not all carnivores are predators. Some carnivores, known as scavengers, feed on the carcasses of already-dead animals. Vultures, for example, are scavengers.
Carnivores or the secondary consumers occupy the third trophic level and the predators that consume the primary consumers occupy the fourth trophic level.
Why are there only 3 trophic levels in food chain?
There is only 10% flow of energy from one trophic level to the next higher level. The loss of energy at each step is so great that very little usable remains after four or five trophic levels. Hence only 4 to 5 trophic levels are present in each food chain.
