Cell Respiration
Energy Transfer
Photosynthesis
Cells break down glucose with oxygen to release energy, CO₂, and water.
ATP Production: Energy from respiration is stored in ATP molecules for cellular functions
Energy Loss as Heat: Not all energy is stored; some is lost as heat during metabolic processes.
Organism Level
Metabolic rate how much energy an organism uses, affecting energy needs.
Energy Flow in Populations: Individual energy needs impact group energy consumption.
Energy Loss Between Levels (Community): Only about 10% of energy is passed up each trophic level; the rest is lost as heat.
