Which sequence represents the levels of organization found in a multicellular organism, from smallest to largest?

The levels of organization in a multicellular organism, from smallest to largest, are typically represented by the following sequence:

1. Cells: These are the basic building blocks of life, the smallest unit of a living organism.

2. Tissues: A group of similar cells that work together to perform a specific function forms a tissue. For example, muscle tissue, nervous tissue.

3. Organs: An organ is a structure that contains at least two different types of tissues functioning together for a common purpose. Examples include the heart, lungs, and liver.

4. Organ Systems: An organ system is a group of organs that work together to perform major functions or meet physiological needs of the body. For example, the digestive system, respiratory system.

5. Organism: All the organ systems of the body working together to maintain life and health form an organism. In this case, the multicellular organism itself.
