Mutualism
The African Bush Elephant and the Olive Baboon have a Mutualism Relationship. Mutualism is when two/both of the species benefit from from a relationship. In my Adaptations page, I talked about how the African bush elephant used its tusks to dig waterholes, when the Olive Baboon senses danger it screeches, and then the African Bush elephant knows that there is danger coming, so the both run away.
Commensalism
The African Bush Elephant and the Dung Beetle have a Commensalism Relationship. A Commensalism Relationship is where one species benefits from either food or shelter, and the other species does not benefit at all. The dung beetle gets a benefit by eating the "dung" from the African Bush Elephant, but the African Bush Elephant does not benefit at all from them.
Parasitism
The African Bush Elephant and the tick have a Parasitism Relationship. A parasitism relationship is when one animal benefits from the relationship and one is harmed. The tick grasps onto the elephant and sucks its blood, so the tick is harming the elephant by taking its blood.
