Warm Up 1. What type of COAL is found in SWPA? 2. What type of COAL is found in central PA? 3. What type of environment was here 350- 240 million years ago? 4. What is the main difference in the types of coal? 5. Limestone is calcium carbonate, where did it come from? 6. Crude Oil is carbon, where did it come from? 7.

Carbon Cycle • The SHORT TERM and LONG TERM carbon cycle transfer carbon through life and earth.
RCC • What is the equation for photosynthesis? • What is the equation for cellular respiration?
PHOTOSYTHESIS • Photosynthesis – Photosynthesis is the process used by plants containing green chlorophyll to utilize sunlight, carbon dioxide and water to form sugar (as glucose) and oxygen. • Sunlight Carbon + Water Glucose + Oxygen Dioxide (Sugar) 6CO2 + 6H2O C6H12O6 + 6O2 + Energy
Cellular Respiration • Cellular Respiration is the process that most living organisms use to obtain energy from glucose (sugar), Oxygen. The wastes formed are carbon dioxide and water. C6H12O6 + 6O2 6CO2 + 6H2O + (Energy)
adenosine triphosphate (ATP) • Many cells (including our own) are capable of generating adenosine triphosphate (ATP) using pathways that either rely upon oxygen (aerobic) or do not rely upon oxygen (anaerobic). • ATP is the form of energy which cells will use to synthesize those molecules needed to keep the cell alive
Aerobic • The use of OXYGEN (aerobic) produces MORE ATP per sugar molecule than without (anaerobic). • Aerobic Respiration causes Organisms to grow much FASTER. • The breakdown of glucose begins with an anaerobic pathway known as glycolysis.
Aerobic Cellular Respiration • Pathways include: • tricarboxylic acid cycle (also known as the citric acid cycle or Kreb's cycle) • electron transport chain • chemiosmosis
Anaerobic • Pathway Includes: Fermentation • Organisms that are incapable of further aerobic breakdown of pyruvic acid carry out fermentation to convert the pyruvic acid down into either : • vinegar (ascetic acid), • alcohol (ethanol) or • one of many other organic compounds
SHORT TERM Carbon Cycle • producers convert CO2 into carbohydrates by photosynthesis • consumers get the carbon by eating the plants, during cellular respiration some goes back in to the atmosphere as CO2. • Carbon is stored in plants and animals and when they die get returned to the earth.
COMPREHENSION CHECK • What is the equation for PHOTOSYTHESIS? 6CO2 + 6H2O C6H12O6 + 6O2 • WHAT is the equation for Cellular Respiration? C6H12O6 + 6O2 6CO2 + 6H2O • What is the connection between the two? Cellular respiration is photosynthesis BACKWARDS • What is the TYPE of Coal found in SWPA? BITUMINOUS • What SEAM is it from (name) Pittsburgh Seam
RCC 1. What type of coal is found in SWPA? 2. What is the equation for photosynthesis? 3. What is the equation for respiration? 4. What type of environment was here 350- 240 million years ago? 5. _______ is the process used by_______ containing green chlorophyll to utilize sunlight, carbon dioxide and _____to form sugar (as glucose) and oxygen.
Comprehension Check • What type of COAL is found in SWPA? • What type of COAL is found in central PA? • What type of environment was here 350- 240 million years ago? • What is the difference in the types of coal? • Limestone is calcium carbonate, where did it come from? • Crude Oil is carbon, where did it come from?
Carbon Cycle • Long Term = fossil fuels are carbon, when they are burned (combustion) for energy CO2 is a byproduct that goes into the atmos. *Forests and oceans are main carbon sinks or carbon reservoirs that accumulate and store carbon. * Carbon is also in limestone CaCO3 although this carbon is derived from shells and bone carbon.

Leading Questions for each cycle… Since we are talking about nutrients moving from living to non living… for each cycle answer these questions: • Where are the nutrients stored? • How does it get into plants? • How does it get into animals? • How does it get back again?
Nitrogen cycle- Atmospheric nitrogen (N2) makes up nearly 78%-80% of air. Organisms can not use it in that form. Lightning and bacteria convert nitrogen into usable forms.
Nitrogen fixation-convert atmospheric nitrogen (N2) into ammonium (NH4+) , N2 NH4+ and then more bacteria use NITRIFICATION to turn it to nitrates and nitrites which can be used to make organic compounds like amino acids.
