Answer: light intensity, carbon dioxide concentration and temperature i think- maybe
Explanation:
Without enough light, a plant cannot photosynthesise very quickly, even if there is plenty of water and carbon dioxide, Increasing the light intensity will boost the rate of photosynthesis and for carbon dioxide even if there is plenty of light, the plant cant photosynthesise if there is insufficient carbon dioxide. and why temperature is because if it gets too cold the rate of photosynthesis will decrease, Plants cant photosynthesise if it gets too hot either
