Buffalo and tick birds exhibit:
a. mutualism
c. parasitism
b. predation
d. commensalism

The answer is mutualism or letter a.  The tick birds ride on the buffalo’s back and eats the tick from its body.  This relieves the buffalo from the insects that suck on its blood.  The birds have  a food source while the buffalo has someone to eat away at the ticks.
