Decomposers Activity 2.2 Overview

Target Student Performance

Students discuss atoms and molecules. Then they use food labels to “zoom into” animal, plant, and decomposer cells to learn that cells are composed of large organic molecules (carbohydrates, proteins, and fats, which have high-energy C-C and C-H bonds), as well as water, vitamins, and minerals (which do not provide chemical energy).
