Ответ:
The reaction can take place only if energy is added.
Explanation:
Exothermic processes are those processes in which heat is released and endothermic processes are those processes in which heat is absorbed.
Photosynthesis is a phenomenon in which green plants containing chlorophyll use sunlight as a source of energy to convert carbon dioxide and water to form glucose and oxygen.
Photosynthesis is the process used by plants, algae and certain bacteria to convert energy from sunlight and turn it into chemical energy in the form of glucose which is used a s a source of energy by many organisms.
Thus photosyynthesis reaction can take place only if energy is added.
