| 11707269703 | Photosynthesis | -light energy into stored chemical energy - sun, CO2, H2O —> O2, C6H12O6 -by plants -in the chloroplast End result is glucose and carbohydrates | 0 | |
| 11707269704 | cellular respiration | -converting carbohydrates into ATP -by All organisms -in the mitochondria and cystoolasm -energy source is carbohydrates -energy result is ATP | 1 | |
| 11707269705 | The Carbon Cycle | -ingredient in carbohydrates, fats, and proteins -found everywhere STEPS 1. Respiration - co2 enters from breathing and burning 2. Photosynthesis- co2 absorbed and o2 enters 3. Consumption- animals due 4. Dentrification- carbon enters atmosphere HUMAN IMPACT -mining -deforestation- vegetation -oceans more acidic -global climate change | 2 | |
| 11707269706 | The Nitrogen Cycle | -component of DNA/RNA -essential for amino acids -the most prevalent component in earths atmosphere -78% of atmosphere STEPS 1. Fixation 2. Nitrification 3. Assimilation 4. Ammonification 5. Dentrification Negative effects Eutrification- algae die- bacteria increase- use up o2 and hypoxia occurs HUMAN IMPACT -fertilizers containing N2 leads to excess nitrates -pollution from combustion release more N2 -sewage dumps large amts in H20 | 3 | |
| 11707269707 | Phosphorus Cycle | -component of DNA/RNA & ATP -phospholipids in cell membranes -limiting nutrient in freshwater STEPS 1. Weathering/Erosion 2. Assimilation -plants take up phosphates from soil 3. Consumption 4. Decomposition- release phosphates into soil 5. Sedimentation- rock Negative effects Eutrophication- algae die- increase in bacteria- o2 used up and hypoxia HUMAN IMPACT - laundry detergents - 17 states banned phosphates from dishwasher detergent | 4 | |
| 11707269708 | Sulfur Cycle | -important in protein and enzyme functioning -necessary for plants and animals STEPS 1. Volcanism-H2S released and converts to SO2/ Algae/Burning of fossil fuels 2 So3 with O2 makes SO3 3. Sulfuric acid and ammonium sulfate created 4. Acid rain 5. Assimilation : plants take up sulfates from soil and animals eat this 6. Dentrification: living things decay and sulfur back in ocean/ rock Cycle HUMAN IMPACT -1/3 of sulfur that reaches atmosphere is from human activity -acid rain | 5 |
