Hope this helped!
Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned.
These global wind systems, in turn, drive the oceans' surface currents. Unequal heating of the Earth's surface also forms large global wind patterns. In area near the equator, the sun is almost directly overhead for most of the year. Warm air rises at the equator and moves toward the poles ((from google))
What process occurs to in the first stage of celluar respiration?
The first stage is called glycolysis. Glycolysis is a process that uses sugar to create ATP molecules
