Answer:
Altering the amount and intensity of light that plants receive
Step-by-step explanation:
Altering the amount and intensity of light that plants receive will drive the rate of reactions of photosynthesis in the plants. This will in turn will lead to plants having a greater capability for yielding more food or fruits through photosynthesis.
However, this altering of the amount and intensity of light in plants should be done adequately, as excessive lighting will reduce the rate of photosynthesis in plants.
