Large quantities of carbon can be released to the atmosphere through geologic processes like volcanic eruptions and other natural changes that destabilize carbon sinks. For example, increasing temperatures can cause carbon dioxide to be released from the ocean.
Carbon cycle begins with photosynthesis which combines sunlight, carbon dioxide from air and hydrogen from water to form carbohydrates. The food thus prepared is either used by plants for growth or stored for energy. When the animals eat plants the nutrients in the plants get digested and carbon is released through exhalation or respiration. Carbon is again released back into the atmosphere when the living organisms die as they decompose again to form carbon dioxide.
