Two butterfly species are competing for the same nectar of a flower in a garden. To survive and coexist together, they may avoid competition in the same garden by:
1. feeding at the same time.
2. choosing different foraging patterns.
3. increasing time spent on attacking each other.
4. predating on each other.
