Detailed explanation-2: -Therefore, a living organism can be defined as anything that has life and consists of cells as its basic unit of organization. Examples of living organisms include humans, fungi, algae, trees, animals, bacteria, protozoa, and insects.

Detailed explanation-3: -For this reason, living things are called organisms. The activities of the cells are controlled by the cell’s genetic material-its DNA. In some types of organisms, called eukaryotes, the DNA is contained within a membrane-bound structure called the nucleus.

Detailed explanation-4: -Birds, insects, animals, trees, human beings, are a few examples of living things as they have the same characteristic features, like eating, breathing, reproduction, growth, and development, etc.

Detailed explanation-5: -A living organism is composed of cells. The cells divide and the body of the organisms show growth due to the increase in the number of cells. A tree is a living organism and shows the process of growth. Road, pen, and water are non-living organisms which do not show the process of growth.
