Actually it is a characteristic of life....everything living must take in nutrients one way or another in order to maintain homeostasis. Trees, take nutrition thru their roots, water and needed soil metabolites, so while they do not eat as humans do, they do take in some sort of nutrition. Even bacteria take in nourishment, and must do so to maintain metabolism. Lack of some form of nourishment causes death.

yes- all things need energy, wither they eat other organisms to get it, or create it themselves. chemosynthesis and photosynthesis.
no- eating is just a habit, there are other ways to get the necessary nutrients like tubes going into your body

it should not
trees don't eat is the simplest argument
