Unformatted text preview: Decomposers ( microorganisms and bacteria) feed on decaying organic matter at all levels in the ecosystem. Solar energy is absorbed initially by the primary producers and stored as chemical energy which is digested by consumers. Only 10% to 50% of the energy at any level is passed on to the next level, consequently the amount of organic matter and consumers must decrease with each level. Photosynthesis is a biochemical reaction which results in the production of carbohydrates and oxygen using water, carbon dioxide, and light energy. A simplified chemical reaction is: H2O + CO2 + light energy = -CHOH- + O2 In the respiration process carbohydrate is broken down and combined with oxygen to create carbon dioxide, water, and chemical energy. A simplified chemical reaction is -CHOH- + O2 = CO2 + H2O + chemical energy...
