Explanation:

In photosynthesis, light energy is used to convert carbon - dioxide and water into glucose and oxygen, and heat is not a necessary input. In cellular respiration, glucose and oxygen are broken down to release energy in the form of ATP, and heat is a waste product generated during the energy - conversion process.

Answer:

D. It is a waste product.
