<u>Answer</u>: The carbon could go into the atmosphere through cellular respiration, it could become part of the acacia tree (biosynthesis), it could die and move to the soil, or an herbivore could eat the leaves of the acacia tree.
This answer contains <em>all </em>the possible routes for carbon.
Carbon originating from 
will either return to the atmosphere due to cellular respiration or become part of the tree. The bio-synthesized carbon can either move into an herbivore through the eaten leaves, or into the soil after the tree dies.
Due to the large amounts of carbon used by for growth, trees are extremely important for the removal and fixation of atmospheric .
Proteins contain 4 calories in every gram, while fats contains 9 calories for every gram, carbohydrates carbohydrates contain 4 calories in each gram. Therefore, 15 grams of carbohydrates contain 15 ×4 = 60 calories, 8 grams of fat will have 8×9= 72 calories and 8 grams of proteins contain 8×4= 32 calories. Hence, the total number of calories will be 60+32+72 = 164 calories
