2) Arrow A represents light energy transformation. Light energy from the sun is converted into chemical energy in plants.
3) Photosynthesis is part of a carbon recycling process in the carbon cycle. Plants absorb light energy and convert it to chemical energy. Plants absorb carbon dioxide which is exhaled by humans and animals. Plants then produce oxygen which is absorbed by humans and animals. Animals also eat plants thus passing the carbon compounds along.
