Answer:
Photosynthesis is a process that releases for oxygen into the atmosphere.
The ocean, living things, rocks and soil are all reservoir of carbon.
Gas, oil and coal are fossil fuels that are primarily composed of carbon.
Step-by-step explanation:
Carbon cycle is a biogeochemical cycle in which carbon compounds are converted and released in the environment. It involved processes where carbondioxide is used with water and light energy in the process of photosynthesis to produce food and release oxygen to the atmosphere. It also involve the process of respiration where carbondioxide is released to the atmosphere after taking in oxygen. It is also involve a process that release carbon when burning of fossil fuels and decay of dead organisms.
Carbo is considered the major composition of living organisms sand it's also the components of biological molecules.
