Mutualism
Mutualism is a type of symbiotic relationship where both involved species benefit from the relationship. An example of mutualism is the Orang-utan and the fruit trees it eats from. The Orang-utan scatters seeds from the trees as it eats the fruit, providing energy to the Orangutan and aiding the trees in growing more. The Orang-utan migrated further inland after the disaster, moving the seeds as well.
