An example for life for an animal and plant are that the both require foods to live. Animals hunt there own food but plants make there own due to photosynthesis. But they are similar because they both require food to continue living. There are many more characteristics but that is just one common one.
Hope this helped.

It might be between plants and water I'm not sure cause I'm on the same question.
You can infer that the birds once had a common ancestor but became separated. Mutations in copying their genes stacked and caused changes in the beaks so the birds could be more well off or better adapted in their new environment.
I would think of a unicellular organism or a plant, but I'm not too sure on this one, Just trying to help :)
