The carbon cycle starts when the plants and trees in the biome conduct photosynthesis. The carbon is taken into plants to create sugars. The plants and trees are then eaten by herbivores. These animals that eat the leaves are then killed and eaten by animals higher up on the food chain. This allows the carbon dioxide to be transferred through the digestion of different animals. Depending on how high up on the food chain, the process continues or the animal dies and is decomposed. The decomposition of the animal releases the carbon dioxide into the soil where it can be stored. The stored carbon dioxide can then be released into the air with combustion and is then moved along back to the plants. Carbon is also transferred along the cycle with the cellular respiration of the animals and the plants. From there, the cycle continues again when the plants absorb the carbon for photosynthesis.
