Answer:
The correct answer is - 2. Giraffe to trees.
Explanation:
In the carbon cycle, the movement of carbon is represented how it moves from one sphere to other and how it transfer among the different organism. The carbon moves from air to the trees in the form of carbon dioxide that is used by trees for the production of glucose by the process of photosynthesis through stomata.
The movement of the carbon among trees to different herbivores including giraffe is transferred by the eating of the leaves or fruits of the tree that carries glucose or starch. The transfer of carbon through giraffe does not take place directly but takes the release of carbon dioxide by the process of cellular respiration to the atmosphere.
