Two or more species adopting same trophic level try to avoid inter-specific competition by selecting different food items under Gause's Principle, which is in the interest of both the species (Odum, 1971).
This leads us to propose that these two ecologically allied species may have adapted to some degree of differential food preference to avoid interspecific competition, under Gause's Principle of competitive exclusion.
