This is a picture of a tree and a poison ivy vine found in my very own backyard. These two organisms have a relationship called mutualism. Mutualism is a type of symbiotic relationship between two species of organisms in which both benefit. The tree benefits by getting protection from the poison ivy. The poison ivy would benefit because it can grow all the way up the tree and reach the top where it will be able to get more sunlight. As you can see in this picture the poison ivy vine is growing up the tree so it can get the sunlight it needs to live. Therefore, this is a mutualistic relationship between the tree and the posion ivy vine where both organisms benefit.
