Answer:
Potential & Kinetic energy.
Explanation:
The water used gains potential energy overtime before it is converted to mechanical (or kinetic energy). This can be explained by the water having increased potential energy as it flows at an equal altitude, but converting to kinetic energy as it flows downhill, or over the dam.
This kinetic (or mechanical) energy is then converted to traditional electricity. This process is also an example of a renewable resource being utilized for everyday things (such as powering cars, homes. or charging batteries).
I'd like to say it's food. However I'm not sure
Organism X existed for a short period of time. I really like geology so trust me, I am 100% sure about this question.
