In the context of competition, "intraspecific" competition occurs among individuals of the same species, while "interspecific" competition occurs between individuals of different species.
-
Male elk fighting over females is an example of intraspecific competition because it involves individuals of the same species (elk) competing for access to reproductive opportunities.
-
A cheetah and hyena fighting over a carcass is an example of interspecific competition because it involves individuals from different species (cheetah and hyena) competing for the same resource (the carcass).
Therefore, the response that describes direct and interspecific competition is "A cheetah and hyena fighting over a carcass."
