Document Summary
Consumers - organisms that get their energy from consuming others. Producers- organisms that convert energy from the sun or chemicals into organic matter. Get their energy through two processes: photosynthesis and chemosynthesis. Processes of photosynthesis and chemosynthesis: photosynthesis - (dominant process) plants use energy from sun to combine carbon dioxide and water into carbohydrates and oxygen - carbs are organic matter - transferred from one to another - phytoplankton, seaweeds. Grams of carbon per meter squared - per year. Process: carbon dioxide and water are converted into carbs and oxygen using energy from the sun chemosynthesis - light from the sun is no longer necessary for reaction to take place. Carbon dioxide and hydrogen sul de - action of breaking the chemical bond of the hydrogen sul de that allow the reaction to take place. Process: carbon dioxide and hydrogen sul de are combined to produce carbohydrates and sulfate using the energy from broken chemical bonds.
