Aerobic: Aerobic respiration takes place in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy. (glucose + oxygen -> carbon dioxide + water). Anaerobic respiration also produces energy and uses glucose, but it produces less energy and does not require oxygen.
The nitrogen cycle could no exist without bactria. bacteria that lived inside the ground, catch the nitrogen that has been fixed and covert it into nitrate.
