what are the characteristics of a living organism?
71002
All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing.

A living organism has to do the 7 characteristics of life, which are states below. Obviously, single-celled organisms do all of these. They move, get nutrients somehow, sense, breathe, reproduce by splitting, and get rid of waste. So yes, single-called organisms are living things.

All groups of living organisms share several key characteristics or functions: order, sensitivity or response to stimuli, reproduction, adaptation, growth and development, regulation, homeostasis, and energy processing. When viewed together, these eight characteristics serve to define life.

Those characteristics are cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, and adaptation through evolution. Some things, such as a virus, demonstrate only a few of these characteristics and are, therefore, not alive.

There is fairly wide consensus that all living things can be recognized by the possession of one or more cells, the ability to metabolize energy from nutrients in the environment or food, the ability to respond and adapt to changes in the environment, the ability to grow, and the ability to reproduce asexually or ...
