Probably glaciers because its cold near the poles and glaciers are made of water
The correct answer is letter B, it creates water reserves. When hydrological power is harnessed it is placed in dams, when these dams are filled, the water then flows into a mechanical turbine that is specific in converting water into mechanical energy. Water in these dams can later on be used for other purposes or for storing energy long-term.
Answer: Energy is passed up a food chain or web from lower to higher trophic levels. This loss of energy explains why there are rarely more than four trophic levels in a food chain or web. Sometimes there may be a fifth trophic level, but usually there's not enough energy left to support any additional levels.
