Competition
Exploitative competition is an indirect form of competition where there is a limited resource controlling the situation. An example would be with trees. The older, taller trees create a canopy effectively absorbing the available light. Thus, the younger, smaller trees do not have access to that resource and are less likely to survive. Interference competition is a direct form of competition where an organism actively interferes with another organism's ability to obtain it's resource. Although there may be plenty of the resource, it's the action of another organism preventing them from getting it. An example would be with American Bullfrogs. They will eat most anything, including younger, smaller bullfrogs. That aggressive behavior takes out competition for the bigger frog's resources.
Describe how it is possibly that species in competition for a resource do not have to come in direct contact with one another
Interspecific : Interspecific competition, in ecology, is a form of competition in which individuals of different species vie for the same resource in an ecosystem (e.g. food or living space). The other form of competition is intraspecific competition, which involves organisms of the same species.Intraspecific : Intraspecific competition is a particular form of competition in which members of the same species vie for the same resource in an ecosystem (e.g. food, light, nutrients, space). This can be contrasted with Interspecific competition, in which different species compete.Source(s):Google Definitions
A.Parasitism occurs when individuals of one species-population are used as a resource by individuals of another species-population.

a.Parasitism occurs when individuals of one species-population are used as a resource by individuals of another species-population. b. An intraspecific version of parasitism, cannibalism, exists.
A sustainable resource
Competition is another relationship that exists between organisms
When a resource is finite (eg food or habitat area), then if more organisms are bread than the food or territory can support, individual organisms have to actively battle one another for the resources.
