![]() Penguins become their prey mainly in winter, when other food sources become scarce not only for seals but also for whales and sharks. The leopard seal it is one of their predators, which can catch them because of their speed in the water. The penguins They are prey for various species, mainly in the water.In their jaw they have sharp teeth that are ideal for chewing and tearing prey, allowing the dolphin to swallow it in one bite. They hunt in groups, in such a way that they can surround a school of their prey. The dolphins they are predators of fish such as herring, sardines and cod.It also has a long tongue that allows it to invade the termite mound. For this, it has powerful claws that allow it to break the termite mounds. The anteater (also called flag bear) is a mammal that feeds on termites and to a lesser extent ants.The polar bear cannot drink water because the one in its environment is salty and acidic. It not only takes the nutrients from its prey, but also the necessary liquid for its survival. It is a predator mainly of the young of seals and of reindeer. It lives in the frozen areas of the northern hemisphere. The Polar Bear it is one of the largest terrestrial carnivorous mammals that exist.While ecosystems and biomes They usually maintain balance thanks to all these biological interactions, including predation, in the case of humans, their predation has reached the extreme of even eliminating species (extinction). In addition, by controlling the number of individuals in the predated group, it prevents an overpopulation. However, predation is critical to survival of the species that works as prey and for its strengthening, since the predators eliminate the weakest individuals of the group. When observing this relationship, we could consider that only the predator benefits. ![]() ![]() For example: the anteater feeds on termites Y ants. The animal that feeds is called predator, while the one who is hunted is called dam. In addition to these types of relationships, there is the biological interaction predation, which occurs when one species feeds on another species. Both species benefit from the relationship, but their existence does not depend on that relationship, as occurs in cases of mutualism. In these cases, they become competitors and hurt each other. For example, two trees that are located close together may need to use nutrients from the soil, moisture, and sunlight. Two living things can require the same resources for their growth. Both agencies benefit from the relationship. If an organism A obtains some benefit (service or resource) from another organism B, while organism B neither benefits nor harms itself, organism A is a commensal. If one organism obtains its food from another and harms it by doing so, it is its parasite.
