Aquatic Food ChainsEnergy flows from the sun through plants and then through each trophic level of a food chain. Food chains start with solar energy captured by green plants that use photosynthesis to produce simple sugars. Oxygen produced as a by-product is an added bonus for all animals!
Only about 10% of the energy in one level of a food pyramid is passed along to the next level as food. Energy is used up in growing, repair, finding food, reproduction and heat loss.
