The input of water cannot estimate photosynthetic rate, since it is also used in transpiration.

(The amount of phosphates in the water. The responding variable was. (The amount of oxygen that the elodea lets off. To measure the responding variable I will use a funnel and a beaker to measure the oxygen given off from the elodea plant.ESULTS. The original purpose of this experiment was to determine the effects of different amounts of phosphorous on the photosynthesis of aquatic plants. The results of the experiment were that as the amount of phosphates in the water increased the amount of oxygen given off of the elodea decreased.
