Mutualism -b. two species interact and both benefit by the interaction.

The interactions among the members of different species are called interspecific interactions. The type of interspecific interactions in which both the species are benefitted is called mutualism. For example, sea anemones and clownfish: This type of interactions shows a symbiotic relationship.

Parasitism - d. one species feeds on another that it lives on or in

The type of interspecific interactions in which the parasite gets benefitted by feeding on their host that is harmed is called parasitism. For example, fleas or ticks that live on dogs and cats.

Types of parasitism include endoparasites, ectoparasites, and brood parasites.

When parasites live inside the body of the host, they are referred to as endoparasites and when they live outside the body of the host, they are called ectoparasites.  The type of parasitism in which the birds lay eggs in the nest of other species so that the young ones receive parental care is called brood parasitism. These types of interactions show a symbiotic relationship.
