A dishwasher uses 700 watts each time it is run. The cycle takes one hour. It is run 150 times per year. How much energy does it use in one year?

• Energy = Power x Time; E = 700W x 150h = 105000 Wh = 105kWh

• Energy = Power x Time; E = 700W x 150h = 105000 Wh = 1050 kWh

• Energy = Power x Time; E = 700W x 150h = 105000 Wh = 1050 J

An addition of a limiting nutrient to an ecosystem may lead to an algal bloom. What effect will this algal bloom have on the oxygen content of the water?

• The algae bloom will cause the oxygen content in the water to increase overall
