Explanation:

Living organisms have characteristics like cellular structure, metabolism, growth, response to stimuli, and reproduction. Viruses like COVID - 19 (SARS - CoV2) lack a cellular structure and cannot carry out metabolic processes on their own. They are considered non - living outside a host cell. Grass is a plant, bacteria are single - celled organisms, and mushrooms are fungi, all of which are living.
