Begin by understanding the hierarchy of biological organization, which is a system used to categorize the complexity of life forms from the simplest to the most complex.
Recognize that the chemical level is the most basic level of organization. It involves atoms and molecules, which are the building blocks of all matter.
At the chemical level, atoms combine to form molecules. These molecules are essential for forming the structures and functions of cells.
The cellular level follows the chemical level, where molecules come together to form cells, the basic unit of life.
Continue up the hierarchy: cells form tissues, tissues form organs, and organs form organ systems, each increasing in complexity.
