Answer:
Competition is a relationship between organisms that has a negative effect on both of them.
Competition occurs naturally between living organisms that coexist in the same environment. For example, animals may compete for territory, water, food, or mates.
In predation, one organism kills and consumes another.
Examples of predation involve carnivorous interactions, in which one animal consumes another like wolves hunting moose, owls hunting mice, or shrews hunting worms and insects.
Commensalism, in biology, is a relationship between individuals of two species in which one species obtains food or other benefits from the other without either harming or benefiting the latter.
For example, tree frogs use plants as protection.
Parasitism is generally defined as a relationship between the two living species in which one organism is benefitted at the expense of the other.
A few examples of parasites are tapeworms, fleas, barnacles, and etc.
A mutualistic relationship is when two organisms of different species "work together," each benefiting from the relationship.
One example of a mutualistic relationship is that of the oxpecker (a bird) and the rhinoceros or zebra. The oxpeckers get food and the beasts get pest control.
