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

Explanation:

a damming a river                increases the supply. Supply side solution. There's more water there.

b desalinating seawater      definitely increasing the supply. You create drinking water from what was not there before.

c invading nation for rivers  increasing the supply (not by much. The people who are there still need their water).

d Raising water prices          reducing the demand

e Tax breaks                          reducing (and maintaining) the demand

f  drip irrigation                      reducing the demand.  

Explanation:

As stated in the above question, supply side solutions increase the supply of fresh water. This means that the options that will increase the level of fresh water that will be offered to the consumer will be on the supply side, that is, those options that will provide plenty of choice for the consumer should be on the supply side, so we can say that the solutions are: desalinating seawater, damming a river to create a reservoir, a nation invading a neighboring country to access their rivers

The above question also states that demand-side solutions will reduce demand for fresh water. This means that these solutions should discourage consumers from paying for or limiting their use of fresh water. These solutions are: raising water prices for consumers and businesses, providing tax breaks for companies that use less water, requiring low-flow shower heads in new homes, replacing inefficient irrigation with more-efficient drip irrigation to grow crops

i think it is dna, i'm not totally sure but i think it might be.

maritime tropical may be your answer.
