2/4/12 Efficiency of Food Production Systems Objective 1: Compare and Contrast Aquatic and Terrestrial Systems Humans depend on food systems in order to survive. These food systems follow the same paths and rules as food chains. Food chains follow the first and second laws of thermodynamics. Energy is lost as it passes through food chain from one trophic level to the next due to decreases in food. In turn there will be fewer organisms at trophic levels as they increase. Food systems are dependent
