Question

An organism is....
A. Anything that is so small you can not see it with your own eyes.
B. An animal that has all the organs that humans have.
C. Any individual form of life
D. A group of things that live and work together in a small environment

Answer 1

The answer is C because an organism is "an individual animal, plant, or single-celled life form" and they all contain life. The answer is not A because humans, dogs, trees, and any other animal, plant, or even bacteria is an organism, and we can obviously see them with our own eyes. In plants, they don't have a heart or lungs like a human, so it's definitely not B. It is not D because there are many animals that do not work together, like some animals hunt, live, and raise children on their own. Plants don't work together as well. The answer can only be C because all organisms are living things.
