Rhizodeposition
Rhizodeposition plays a very important role in connection with the carbon cycle. Out of all the carbon that the plant absorbs through photosynthesis around 25% of the carbon will be released through the roots of the soil, this carbon is what many of the microorganisms feed on in regards to rhizodeposition. Without this exchange of carbon, the microorganisms would not have one of the most important building blocks to life and would likely die. Similarly, the plants would significantly lack the antibiotics, hormones, enzymes and phosphates required to survive and would either die or be very weak.
