- Photosynthesis is the process by which plants convert light energy into chemical energy (glucose) using carbon dioxide and water, releasing oxygen as a byproduct. - Respiration is the process by which organisms break down organic molecules (like glucose) to release energy. Aerobic respiration requires oxygen and produces carbon dioxide and water. - The question describes a gaseous product (oxygen from photosynthesis) being a requirement (for respiration) of a process that releases energy.
The gaseous product of a process in plants is a requirement for another vital process that releases energy. Given below are four combinations of the process and product. Identify the correct answer.
