Verified step by step guidance

Begin by understanding the hierarchy of biological organization. In biology, the organization of living organisms is structured in a hierarchical manner, starting from the smallest unit to the largest.

Recognize that atoms are the smallest unit of matter and combine to form molecules. Molecules are groups of atoms bonded together, representing the smallest fundamental unit of a chemical compound.

Identify that cells are the basic structural and functional units of life. They are composed of molecules and are the building blocks of tissues.

Understand that tissues are groups of similar cells that work together to perform a specific function. Examples include muscle tissue, nervous tissue, and epithelial tissue.

Finally, realize that organs are structures composed of two or more types of tissues that work together to perform specific, complex functions. For example, the heart is an organ that includes muscle tissue, connective tissue, and nervous tissue, all working together to pump blood.
