Your physiology is your body and the way it works; your behaviour is the way that you act. Evolution has shaped both of those. So a physiological adaptation for one of Darwin's finches might be, for instance, the way its beak is shaped to crack open the nuts that it finds in its environment. A behavioural adaptation causes it to have a natural instinct to crack the nuts.

Closer to home - when a human being is hungry, a bunch of physiological adaptations cause their metabolism to slow down and start freeing up stores of energy in fat deposits and in the liver. A behavioural adaptation causes them to go find some food.

So would you say:
Anatomical adaptation- structure
Physiological adaptation- how it works
behavioural adaptation- how it acts
?? I don't really know how I can put it into better words

Those are the general principles. But because we're talking about adaptations in particular here, if you want to give a definition, it's how those features are suited to the organism's environment.
