Photosynthesis Plants use sun to make glucose Photosynthesisers are base of food chain Too much algae? You got problems Need water Sunlight Nutrients Fertilizer runs into water, increases nutrients, too much algae Too much fish food/waste also does this Dead zone - an area in ocean or lace with scant or little oxygen Increased nutrients Increased algae growth Increased O2 from algae photosynthesis during day At night, respiration decreases O2 Uses up nutrients and die Decomposing bacteria consume/decompose algae Bacteria then blooms Oxygen is decreased even further Anoxic conditions - marine life cannot be supported Organic must have carbon AND hydrogen Chloroplasts - organelles consisting of photosynthetic pigments, enzymes, and other molecules grouped together in membranes
