evolution - Are there any multicellular forms of life which exist without consuming other forms of life in some manner?

The title is the question. If additional specificity is needed I will add clarification here.

Are there any multicellular forms of life which exist without requiring the consumption (destruction) of other forms of life in some manner? Thus purely on inorganic material.

I do understand that the definition of life is a semantic distinction, so for this discussion I will assume the one Wikipedia provides:

"Life is a characteristic distinguishing physical entities having signaling and self-sustaining processes from those that do not, either because such functions have ceased (death), or because they lack such functions and are classified as inanimate. Biology is a science concerned with the study of life."

I am open to considering alternative suggestions.

Thank you.
