This relationship between the plant and the animal represents mutualistic symbiosis; they have a symbiotic relationship which is mutualistic.
Plants benefit by having their seeds dispersed to farther areas when animals eat their nutritious fruits. So, animals gain from the plants since they are able to attain nourishment for themselves. Both benefit from each other at the same time when an action is done, and so, their relationship is mutual.
Hope this helps! :)
