-Cells: the basic structural and functional units of an organism. 3. The particles and enzymes used to drive reactions and processes in an organism are made up of chemicals, as are the structural components of the living cell. The brain then sends signals that allow the body to shiver or sweat and take conscious action to change our temperature. Tissues are groups of cells and materials surrounding them, Tissues are joined together to form organs, A system consists of related organs with a common function, An organism or any living individual; all parts of the body functioning together, David N. Shier, Jackie L. Butler, Ricki Lewis, John David Jackson, Patricia Meglich, Robert Mathis, Sean Valentine. Chemical level is the simplest level within the structural hierarchy. An organ system is a group of organs that work together to perform a specific function (for example, the stomach, small and large intestines are all organs of the digestive system, that work together to digest foodstuff, move nutrients into the blood and get rid of waste). The levels, from smallest to largest, are: molecule, cell, tissue, organ, organ system, organism, population, community, ecosystem, biosphere. What are the six different major levels of the organization from smallest to largest that ecologists commonly study?
