Answer:
No man is an island.” This saying is also true for organisms in an ecosystem. No organism in the world exists in isolation. Individual organisms live together in an ecosystem and depend on one another for survival . They have many different types of interactions with each other, and many of these interactions are critical for their successfull survival.
Competition: Competition occurs when two organisms compete for the same resource (food, space, mates, etc.). Both individuals are negatively impacted by competition for the resource because either the resource is limited or, if the resource is not limited, they can physically interfere with competitors attempting to obtain the resources.Organisms of the same species compete for a variety of reasons, including a lack of food,space and mate resources. This type of competition serves to limit a species' population and thereby ensure its sustainability and survival.
