Competition between cow and goat for scarce grasses during dry season can be described as

Competition is an ecological interaction in which organisms struggle for the same limited resources, such as food, water, or space. It is classified into two types based on whether the competing organisms belong to the same or different species.

Interspecific competition occurs between organisms of different species that require the same resources. A cow (species Bos taurus) and a goat (species Capra aegagrus hircus) are two distinct species. When they both graze on scarce grasses during the dry season, they compete for the same limited food resource across species boundaries. This is therefore interspecific competition.

Intraspecific competition occurs between members of the same species - for example, two cows competing for the same grass. Since the question involves a cow and a goat (different species), it is not intraspecific. Predation involves one organism killing and eating another, which is not the case here. Commensalism is an association in which one organism benefits and the other is unaffected, which does not apply to a struggle for scarce resources.

Exam tip: The prefix inter- means "between" (different species), while intra- means "within" (same species). Always check whether the competing organisms belong to the same or different species before choosing.
