Reason: We will make a few changes to the plant’s environment to affect the rate of photosynthesis. Refer to your photosynthesis equation and think of one change you could make to this setup that would decrease the rate and one change that would increase the rate. Note: the plant needs to stay in the water!

For the strategies below, decide whether they are best described as demand-side solutions or supply-side solutions to meeting human needs for fresh water. remember that a demand-side solution reduces demand for fresh water, whereas a supply-side solution increases the supply of fresh water. (a) damming a river to create a reservoir (b) desalinating seawater (c) a nation invading a neighboring country to access their rivers (d) raising water prices for consumers and businesses (e) providing tax breaks for companies that use less water (f) replacing inefficient irrigation with more-efficient drip irrigation to grow crops (g) requiring low-flow showerheads in all new homes
