Answer:
You, a human being and a pet share a mutualistic relationship. A mutualistic relationship is a relationship in which two different species of organisms benefit each other. You and your pet have a mutualistic relationship because a pet provides companionship, comfort, in some cases protection (depending on the pet), and protecting your home from rodents (also depending on the pet). While animals provide these services for humans, in return we provide food, water, shelter, and love/comfort for the animal. Both organisms (you and your pet) benefit from your relationship therefore it is mutualistic.
