the oxpecker is a bird that rides on the buffalos back, and eats the flies and other insects off its back. its very nice of the little birdy. :)
I believe the term you're looking for is symbiosis. :)
the back
A Mutualistic relationship between organisms is a relationship by which both organisms benefit from the other. An example of this would be the hippopotamus and the Oxpecker (bird). The birds sit on the hippo's back, getting free food by eating parasites that bother the hippo, while the birds are protected by the hippopotamus. - Dabigb such relationship is called symbiosis. Symbiotic Symbiosis/mutualism. mutualism
The question is describing a 'symbiotic' relationship. The condition in which the two species find themselves is called 'symbiosis'. Ex. a hippopotomus has folds in its skin and bugs get into them. The oxpecker bird gets the bugs out of the folds of skin, this way, the oxpecker bird eats and the hippo stays healthy and bug-free so both sides benefit.
The rhinoceros lives in a symbiotic relationship with an oxpecker. Their symbiotic relationship is mutualism, meaning thy both benefit from this relationship. the oxpecker cleans off bugs and ticks from the rhinoceros, that gives the oxpecker nutrients and the rhinoceros gets clean
In the past it was believed to be Mutualism but the current standing on this issue is that they are a semi-parasitic relationship. This is because the oxpecker gets food and the hippo gets cleaned, but the oxpecker also picks at the cut to keep it open and get more food. This makes it more prone to infection and it also continues to hurt the other animal.
oxpecker
the rhino has a symbiotic relationship with the oxpecker bird, or also called a tick bird. they pick the ticks off of the rhino's back and eat them, the bird gets food and protection, while the rhino gets the tick off it's back
tick birds eat the ticks on a rhino. the relationship is positive for both the rhino and the tick bird because they both get what they want.
Hippo ! why would you eat a bird poop.Though hippo is difficult to eat.
the relationship is paratism.
parasitism

The relationship between the Flicker bird and the cactus is an example of symbiosis in the desert. The bird makes it's nest in the dead crevices of the cactus and does not harm it.
