Large predators like lions , cheetahs, bears, wolves, crocodiles, and cougars are all good examples of secondary consumers. These carnivorous animals feed exclusively on other animals, which might sometimes be bigger and heavier than the predator.
For instance, lions are renowned for attacking and eating larger prey like buffalos, baby elephants, hippopotamuses, and wild beasts. Additional reading: Do Lions Eat Elephants? Small and medium-sized creatures such as rats, frogs, lizards, raccoons, snakes, and bobcats can also fall under secondary consumers though they may not entirely be carnivorous.
They feed on primary consumers such as insects, caterpillars, and earthworms. Some even eat other secondary consumers. For instance, some snakes eat frogs and rats, which many people consider to be secondary consumers. You might not know this, but fish are predominantly carnivorous with very few species regarded as herbivores.
Carnivorous fish like sharks, piranhas, sea lions, and seals eat crab, prawns, squids, salmon, and other fish that are smaller than them. Birds can either be herbivores, carnivores, or omnivores. Birds of prey like kites, eagles, hawks, and owls are fully carnivorous. They are considered secondary consumers since they eat other animals like rabbits, rats, fish, reptiles, and carrions.
Other birds of prey like vultures eat carcasses. They do not attack live animals. Yes, and No — most humans are not secondary consumers, but tertiary consumers. This is because they not only feed on primary and secondary consumers, but also eat primary producers plants.
Nonetheless, people who decide to eat plants only vegans and vegetarians are primary consumers while humans who feed on meat are secondary consumers. Animals that eat secondary consumers are carnivorous and are often called tertiary consumers or apex predators since they exist at the top-most level of the ecological food chain.
They rarely have predators but their bodies will be consumed by scavengers once they die. Then again, tertiary consumers rely entirely on primary and secondary consumers to survive. Top carnivores in the ecosystem are also called apex predators. In temperate regions, for example , you will find secondary consumers such as dogs, cats, moles, and birds. Other examples include foxes, owls, and snakes. Wolves, crows, and hawks are examples of secondary consumers that obtain their energy from primary consumers by scavenging.
Humans are considered as consumers because they neither depend on plants completely for their food nor they depend fully on other animals also they do not make their own food but they require both plants and animals for their food. Secondary consumers - insects are eaten by frogs. The frogs are the secondary consumers in this food chain. They obtain part of the energy stored by the insects. The main difference between primary secondary and tertiary consumers is that primary consumers are the herbivores that feed on plants, and secondary consumers can be either carnivores, which prey on other animals, or omnivores, which feed on both animals and plants, whereas tertiary consumers are the apex predators.
Humans are said to be at the top of the food chain because they eat plants and animals of all kinds but are not eaten consistently by any animals. The human food chain starts with plants. Plants eaten by humans are called fruits and vegetables, and when they eat these plants, humans are primary consumers.
Humans are dominant consumers. They affect food webs through energy production and agriculture, pollution, habitat destruction, overfishing and hunting. Also their demands for food and shelter along with population growth, affecting soil and aquatic ecosystems. Any individual who purchases products or services for his personal use and not for manufacturing or resale is called a consumer.
Consumer refers to any person who purchases some goods for a consideration that has been either paid or promised to pay or partly paid and partly promised.
First - level , primary , Consumers They eat organisms who make their own food through photosynthesis, as you now already know, they include algae, plants, and bacteria. Primary consumers can either be herbivores or a omnivores.
Primary consumers interact with producers and second- level consumers. Each link in this chain is food for the next link. All food chains start with energy from the sun. This energy is captured by plants. Thus the living part of a food chain always starts with plant life and ends with an animal. Plants are called producers because they are able to use light energy from the sun to produce food sugar from carbon dioxide and water. They are called consumers. There are three groups of consumers.
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.
Animals and people who eat both animals and plants are called omnivores. Then there are decomposers bacteria, fungi, and even some worms , which feed on decaying matter. These decomposers speed up the decaying process that releases mineral salts back into the food chain for absorption by plants as nutrients. In a food chain, energy is passed from one link to another. When a herbivore eats, only a fraction of the energy that it gets from the plant food becomes new body mass; the rest of the energy is lost as waste or used up by the herbivore to carry out its life processes e.
Therefore, when the herbivore is eaten by a carnivore, it passes only a small amount of total energy that it has received to the carnivore.
The carnivore then has to eat many herbivores to get enough energy to grow. Because of the large amount of energy that is lost at each link, the amount of energy that is transferred decreases each time. The further along the food chain you go, the less food and hence energy remains available. The above energy pyramid shows many trees and shrubs providing food and energy to giraffes. Note that as we go up, there are fewer giraffes than trees and shrubs and even fewer lions than giraffes.
As we go further along a food chain, there are fewer and fewer consumers. In other words, a large mass of living things at the base is required to support a few at the top. Many herbivores are needed to support a few carnivores. Most food chains have no more than four or five links. There cannot be too many links in a single food chain because the animals at the end of the chain would not get enough food and hence, energy to stay alive. Most animals are part of more than one food chain and eat more than one kind of food in order to meet their food and energy requirements.
These interconnected food chains form a food web. Food chains can get complicated because animals usually eat a variety of food. Cut enough strips of paper so that each student will have four. Cut the yarn into pieces that will connect species that interact with each other. Ask students to name some species under each heading. Then demonstrate how to create a food chain, using some of the species listed.
The crustaceans are eaten by fish which are eaten by seals. The seals are eaten by polar bears. The polar bear food chain has five organisms. You can find many other food chain examples of varying lengths with a little research. Most human food chains have only three organisms because humans generally do not eat carnivores.
While there are exceptions, especially for marine carnivores, most human food is plant-based or based on the consumption of herbivores. For example, meat is a major food group for humans. Meat is usually beef, chicken, turkey or pork. These animals are all primarily herbivorous, and even if pigs are omnivores, for human consumption they are fed mostly plant material. As a result, the human food chain for meat is only three organisms long: plant producer, herbivore and human consumer.
For food harvested from the sea, the human food chains can be more complicated. A simple three-organism human food chain is made up of algae as the producer, shrimp as the primary consumer and humans as the secondary consumer. A longer food chain is that of humans eating tuna, which eat other fish that, in turn, may eat smaller fish until the smallest fish eat algae.
