An example of an ecological niche is that of the dung beetle. Tropical rainforest diversity. In spite of the different conditions, sometimes fighting to dominate the territory producing a competition between two same species known as interspecific competition, which gives the strongest the highest hierarchy. Within a forest, a population of sparrows feeds on berries that grow abundantly on bushes. Resource partitioning to reduce competition.
