Define living things and nonliving things and dead organisms?

Answer 1

Living things are living, breathing, eating organisms that take and contribute to their ecosystem. Nonliving things do not breathe, eat, or need water (e.g., a rock). A dead organism is a once-living creature that has become a nonliving thing.

Answer 2

Living things are organisms that have the ability to grow, reproduce, respond to stimuli, and maintain homeostasis. Nonliving things are objects or materials that do not possess these characteristics. Dead organisms were once living but have ceased to exhibit any signs of life.
