Graph A above demonstrates that the rate of photosynthesis Adecreases in response to increasing light intensity
B)continues to increase exponentially (continuously) in response to
increasing light intensity
C)increases in response to increasing light intensity but only to a certain
point
D)is not affected by light intensity

C)increases in response to increasing light intensity but only to a certain

point

The intensity of photosyntheis increases until the intensity of light reaches 50000 luxes after 100000 luxes the rate of photosynthesis will decrease because the intense light damages the tissues.

It depends on how the signals are transmitted in our body. Signals have two ways of travelling through our body : through nerves and through hormones. While nerves transmit electrical signals, hormones are more like chemical messengers.
