The Carbon Cycle https://www.youtube.com/watch?v=dDBU0lg-HYE

Photosynthesis The process of converting light energy into chemical energy, and storing it in the bonds of sugar. This process occurs in plants and some algae. Plants only need light energy, CO2, & H2O to make sugar. Takes place in the chloroplasts of the cell, using the green pigment called chlorophyll. 6CO2 + 6H2O + Light Energy  C6H12O6 + 6O2 http://www.youtube.com/watch?v=wj8TGhcCnxs http://www.youtube.com/watch?v=pE82qtKSSH4

Photosynthesis

Cellular Respiration The process cells use to generate energy in the form of ATP, adenosine triphosphate, from food molecules and release waste products. Oxygen is required to generate this energy. The products of respiration are the reactants of photosynthesis and vice versa; they are a complementary reaction. C6H12O6 + 6O2  6CO2 + 6H2O + 38ATP

Global Warming Climate Change: Any substantial change in the Earth’s climate that lasts for an extended period of time. Greenhouse gases: Gases that act like a greenhouse around the Earth. Example: CO2, CH4, and water vapor. Greenhouse Effect: The trapping of solar radiation by the Earth’s atmosphere, caused by the presence of greenhouse gases in the atmosphere.

Global Warming Global Warming: Climate change that causes an increase in the average temperature of the atmosphere near the Earth’s surface and in the troposphere (the lowest layer of the Earth’s atmosphere.) http://www.youtube.com/watch?v=OqVyRa1iuMc http://www.bbc.com/earth/story/20141030-polar-bear-season-in http://www.bbc.com/earth/story/20141107-will-polar-bears-become-extinct
