What is an example for commensalism and paratism and mutualism?

Mutualism is the biological interaction between two species of organisms, in which both parties benefit. It can be as simple as bees getting nectar from flowers while also pollinating them, or more specific such as the relationship between the Egyptian plover birds and the Nile crocodiles (the birds eats off the decayed meat on the crocodile's teeth, and in so doing, provide much needed dentistry).

Some other examples:
Clownfish and sea anemones
Some species of ants and acacia
Honey guide (a species of birds) and honey badger
