What light intensity and co2 level do you think will maximize the rate of photosyntesis?

The optimal light level for photosynthesis is 10,000 Lux. Lux is a unit for measuring light intensity. Low light intensity tends to lower rate of photosynthesis. However after reaching an intensity of 10,000 Lux, there is no increase in the rate. Carbon dioxide concentration in the atmosphere ranges from 0.03 to 0.04 %. It has however been determined that 0.1% of carbon dioxide in the atmosphere significantly increases the rate of photosynthesis . Therefore supplementing CO2 to the existing amount will speed up photosynthesis and plant growth rate will increase.

The best way to tell its true color is to look at the minerals streak

Dis the correct answer thats what i put and it was right
