nitrogen released from dead matter goes into soil, helping/feeding the plants, who in turn give us oxygen

The Nitrogen Cycle uses excretion to make NH3 (ammonia) Important processes in the carbon cycle are photosynthesis, deposition, and DECOMPOSITION. ... Carbon is then passed into the food chain and returned to the atmosphere by the respiration and decay of animals, plants, and other organisms.
