Question

part b
which one of the following statements is correct?
sugar and oxygen gas are the outputs of photosynthesis and the inputs of cellular respiration.
co₂ and h₂o are the outputs of photosynthesis and the inputs of cellular respiration.
co₂ and h₂o are the inputs of photosynthesis and also the inputs of cellular respiration.
sugar and oxygen gas are the inputs of photosynthesis and the outputs of cellular respiration.

Explanation:

Photosynthesis uses carbon - dioxide ($CO_2$) and water ($H_2O$) along with light energy to produce sugar and oxygen gas. Cellular respiration uses sugar and oxygen gas to produce carbon - dioxide ($CO_2$) and water ($H_2O$) along with energy. So sugar and oxygen gas are the outputs of photosynthesis and the inputs of cellular respiration.

Answer:

Sugar and oxygen gas are the outputs of photosynthesis and the inputs of cellular respiration.
