Biology is the natural science that studies life and living organisms, including their physical composition, chemical processes, molecular interactions, physiological processes, development, and evolution. The main idea behind biology is that the cell is the basic unit of life.
Biology is the study of the cycle of life from birth to death. It focuses on living organisms and how they survive, whether in captivity or within a populated area. It is the study of organisms that were once alive, whether it is a plant, animal, or microorganism.
Biology is essential because it helps us understand how living organisms work and their relationship with each other and the environment. Biology covers a wide array of topics. These include biochemistry, ecology, genetics, and physiology.
