Answer 1

A falcon was killed by an owl, not the other way round - there is a mistake in your question. 
However, the likely significance of these events is that they highlight the disruption of the natural order caused by Macbeth's crime.
Usually, a falcon can kill an owl, and horses don't normally eat each other. But since Macbeth has killed the king, he has disturbed the order in nature and thus these strange things happen.
