Is pine needle a good material in yard compost?

Yes - it is a great carbon source!

Is it easy to be broken down?

% v5 I( m! W0 r9 x$ W% oNo, it breaks down slowly because of its high C:N. It makes a very attractive mulch as well, so if you have a lot of it I suggest spreading it on top of autumn leaves around trees or shrubs, or at the back of the bed where weeding is a chore.
