How does the Amount of CO2 Affect the Rate of Photosynthesis? There are a number of variables that can affect the photosynthesis rate of Canadian water weed (Elodea). They are as follows:  The amount of light: an increased light level increases the rate of photosynthesis to a certain point where at another factor limits the photosynthesis rate.  The temperature: Increased temperature increases the rate of photosynthesis to a certain temperature‚ after which‚ essential enzymes

through the battery from the negative terminal to the positive terminal. The battery raises the potential of the charge by‚ so the work the battery does on the charge is. The total amount of charge‚ which flows through the battery per unit time‚ is‚ by definition‚ equal to the current flowing through the battery. Thus‚ the amount of work the battery does per unit time is simply the product of the work done per unit charge‚ and the charge passing through the battery per unit time‚ In other words‚ a mechanical
