The prey is the resource for which the two different flea species in the same forest would likely to compete with each other. This is because of the fact that prey is the source of food which is the basic need required for the survival of both the flea species. Other needs like mates, space and hosts are secondary needs, the two flea species would probably survive without them. If the prey population is small then the competition among the members of the two different flea species will increase.
Baboons, sparrows, and human beings are considered both primary and higher order consumers because they all eat plants and meat. Primary consumers feed on producers/ plants. Then secondary consumers feed on primary consumers.
