The tree and the soil in this picture are a wonderful example of a mutualistic relationship because in this soil are many worms. Earth worms to be exact. These worms burrow through the soil mixing it up helping the plant get the nutrients it needs. In addition the worms are able to get the food and shelter they need to survive. Also, the scat of the Earth worms are filled with the nutrients the tree need to survive. This is a perfect example of a mutualistic relationship because both species are benefiting from what each other does and so this is a symbiotic relationship.
