Recent research suggests that the collection of all gut bacteria in an individual can have a widespread impact on the host’s metabolism, immunity, and well-being. The bacteria aid in digestion and provide protection against the invasion of pathogenic bacteria. The interaction between humans and their gut flora is a classic case of mutualism. Over time, the host tree dies and the strangler fig appears as a tree with a hollow central column. Their seeds germinate in the crevices of other trees, and they derive their nutrition by dropping roots into the bark of the host tree, rather than into the soil. Strangler figs are common tropical plants that behave like parasites. Parasitism is also seen in the plant kingdom. Filarial worms are parasites that cause skin, eye,and lymphatic diseases. Tapeworms are common human parasites that can cause malnutrition, especially in young children. The infection and causes cyclical rounds of high fever and chills, and can even kill the host. The parasite that causes malaria, Plasmodium, infects a wide variety of animal hosts, including reptiles, birds, and mammals. Krill are crucial to the health of the ecosystem because they are the main natural food source for many fish as well as large mammals like blue whales. In marine environments, krill are small crustaceans that feed on the primary photosynthetic organism of the ocean – phytoplankton. The herbivores usually move around 300 feet (91 meters) away to resume feeding. In addition, the acacias also release ethylene gas, which signals to trees in the vicinity to pump toxins into their own leaves. When giraffes feed on acacia trees, the trees release a toxic substance into their leaves that forces the giraffes to move away from them. Plants have been known to develop defenses against grazing. They also contain microorganisms in their gut to digest plant-based carbohydrates. For example, elephants have large flat teeth to grind tough plant material. Herbivores are adapted to their mode of feeding. Grazing is a form of herbivory where the plant regenerates the parts that were eaten by the herbivore. One exceptional and unusual form of carnivorous predation is cannibalism, where individuals consume members of their own species. Insectivores are often found in regions where the soil is not rich in nutrients. A pack of Asiatic wild dogs can pursue and hunt large bison that are nearly 10 times the size and weight of a wild dog.Ĭarnivorous predation is also seen in the plant kingdom, among insectivores such as pitcher plants and Venus flytraps. For example, lions coordinate in groups to ambush and take down large herbivores such as zebra and rhinos. While many carnivores hunt prey that are much smaller than themselves, some cooperate with other individuals of their species to bring down larger prey. The wolf is a well-adapted predatorĬarnivorous predation can also be an interaction between two groups of organisms. They are particularly well-adapted hunters, with strong jaws, heightened senses, and powerful bodies, they can identify and chase prey at high speeds. Wolves are large canines that primarily hunt large herbivores such as deer, elk, and sheep. Examples of Predation Carnivorous Predation However, the host is not harmed and the interaction is mutually beneficial. Mutualism involves the interaction between two organisms where the host provides the nutrition and space for the growth and reproduction of another species. In most cases, the parasite is much smaller than the host. However, unlike carnivory, the host is not always killed. In many successful parasitic interactions, the host suffers a loss of energy, falls sick, or loses access to nutrients. Parasitism is a form of predation where the host supplies essential nutrients for the sustained survival and reproduction of the parasite. Tough seed coatings are removed in the digestive tract of the herbivore, and its dung fertilizes the soil, providing an ideal environment for seed germination. Fruit seeds are dispersed over wide areas as the herbivore moves. Occasionally, herbivory can benefit the plant as well. Unlike carnivory, not every herbivorous interaction leads to the death of the plant. Herbivorous predation involves the consumption of autotrophs, such as plants or photosynthetic algae. However, carnivorous predation is widespread in the animal world and carnivores can come in a variety of sizes – from sea otters hunting sea stars to blue whales consuming zooplankton, each carnivore is adapted to its mode of feeding. The common perception of carnivory involves a large animal, such as a shark, tiger, or wolf hunting smaller animals like rabbits or deer. Carnivorous predators kill and eat their prey.
