Well the only addition is that there should be an arrow pointing from the trout to the mayfly nymph. The first correction is that the arrow in between the trout and dragonfly nymph should be flipped because the dragonfly nymph gets eaten by the trout, not the other way around. The second correction is that since the dragonfly nymph eats the mayfly nymph, the arrow between them should also be flipped. Now you just need two explaining sentences:)

This is a very easy one the answer is C ;)
