Detailed explanation-1: -Answer and Explanation: The correct answer is (b) One species uses another species as food or shelter causing harm.
Detailed explanation-2: -Although parasitism and predation both have a +/-effect, they are not the same. In predation (or herbivory), the prey is consumed by the predator. Parasitism is different from predation in that the negatively affected species is not eaten or killed during a single feeding.
Detailed explanation-3: -The correct answer is (C) +/+. Mutualism is a type of symbiosis in which both species benefit from the relationship. In a way, the species are mutually benefitting each other. When denoting symbiotic relationships, a “+” symbol indicates that an organism benefits from the relationship.
Detailed explanation-4: -A parasitic relationship is a relationship between two different organisms in which one organism gains at the expense of others without killing it. An example of a parasitism relationship is that of ticks, fleas, lice or leeches on a host such as a human or a dog.
