How does light intensity affect the rate of photosynthesis?

re slowly.I think that as we move the lamp away (and therefore reduce the light intensity) from the elodea pondweed the number of bubbles produced will decrease steadily. For instance, say at 10cm dis ... ween 0-50°C, but then it should decrease dramatically from 50-100°C.PlanApparatus*desk lamp*Elodea pondweed x 2*boiling tube x 2*paperclip x 2*250ml glass beaker x 2*test tube rack*thermometer ...
