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 …

…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.
