Interspecific competition occurs between individuals of different species competing for the same limited resources. In this scenario, cows and goats are two different species both requiring the scarce grasses for survival during the dry season.

A. Intraspecific refers to competition between individuals of the same species, for example, between two cows, or two goats.

B. Predation is an interaction where one animal (predator) hunts and kills another animal (prey) for food, which is not what is happening as both are herbivores eating grass.

D. Commensalism is a relationship where one species benefits and the other is neither significantly harmed nor benefited. This is not the case as both species are negatively affected by the scarcity of grass.
