Question

Which of the following best describes ALL the possible places carbon can go once it is in an acacia tree in the savanna?

Answer 1

Answer: 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 all the possible routes for carbon.

Carbon originating from $CO_{2}$ 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 $CO_{2}$.
