Verified step by step guidance

1. Step 1: Understand the concept of biological organization, which refers to the hierarchy of complex biological structures and systems that define life, ranging from the smallest unit to the largest.
2. Step 2: Recognize that the smallest level of biological organization is the molecule, which includes atoms and chemical compounds essential for life, such as DNA and proteins.
3. Step 3: Identify the next level as the cell, which is the basic unit of life and the smallest structure capable of performing all life processes.
4. Step 4: Progress to the tissue level, which consists of groups of similar cells working together to perform specific functions, such as muscle tissue or nervous tissue.
5. Step 5: Continue to the organ level, where tissues combine to form organs that perform specialized functions, and finally to the organism level, which represents the complete living entity capable of independent existence.
