C. It harms aquatic organisms
Explanation:
The hydropower is a one of the most commonly used in the world. It is based on the power of the water, and by building a dam on a river, the water is accumulated, and its power used for production of electrical energy. While this type of power has lot of advantages, like having long lifespan, being eco-friendly, and it has high efficiency, it also has some negatives about it. The biggest negative by the hydropower is that it causes harm tot he aquatic organisms. Because there is a dam built, the water becomes more stagnant, meaning that it becomes warmer, harming the organisms that are not able to adapt to it. The dam restricts the migration of the aquatic organisms, which is especially a big problem for the ones that migrate because of mating. The nutrients start to concentrate in front of the dam, while after the dam they are in very low quantity.
