Answer 2

Answer:

We can ask the same question to ourselves

Explanation:

Don't be confused.

Respiration is a common process undertaken by all. In aerobic respiration the needs remain the same, oxygen, as oxygen helps us oxidize the food to release energy.

The same is the case with plants. They too use photosynthesis to produce food but the food needs to be oxidized as well which cannot be done by carbon dioxide.
