Bio- Interactions Among Species

In a community, there are many different interspecific interactions between species. Each interaction has a different effect on the community and the population density. These interactions illustrate how certain species live among other species in a community and show how each species is affected by it. Specific relationships between certain species are predation, commensalisms, and mutualism. Each relationship has either a positive, negative, or neutral effect on each animal.

The most marked population interactions are those involving predation. Predation is the capturing and eating of prey by a predator. The typical image of predation is a lion catching its prey, although it is certainly not the only type. Although many people envision predation as a fox hunting and eating a rabbit, there are other types of positive/negative interactions, such as parasitism and herbivory, which include a predator and the eventual killing of an entire organism. Predators have many important feeding adaptations that are evident and recognizable. Most predators possess keen senses that permit them to recognize and locate the organisms they feed on, or their prey. Predators also exhibit adaptations which assist catching, restraining, and masticat


Predation, commensalism, and mutualism, are all different types of close interactions between species in a community. The effect of each one is that at least one of the partners benefits from the relationship. The predation relationship has a positive/negative effect, commensalism has a positive/neutral effect, and mutualism has a positive/positive effect. Each form also causes adaptations in the partner, or partners, that is benefiting from the association. As a result, the adaptations help to improve the fitness of the animal and therefore increase its reproductive success.

Another form of symbiosis is mutualism, where both partners benefit from the relationship. In mutualistic relationships, the evolution of adaptations in both participating species are required because changed in either species are likely to affect the survival and reproduction of the other. Some coevolved mutualistic adaptations are nitrogen fixation by bacteria in the root nodules of legumes, the digestion of cellulose by microorganisms in the gut of termites, and specific interactions of certain pollinators and flowering plants. Many mutualistic relationships may have evolved from predator-prey or host-parasite interacti
