D. Hydropower can harm native aquatic populations.
Explanation:
Hydropower is the power of water or hydrosphere and is the cheapest and simplest form of energy.
The hydrosphere is a renewable source of energy and is thus non-polluting but most of the hydropower that is converted into electricity is harmful to the marine and aquatic life forms.
As it disturbs their habitats and created chemical and physical change in the body of water. Such as depletion of oxygen and enrichment of nutrients.
These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division. Acquired mutations in somatic cells (cells other than sperm and egg cells) cannot be passed to the next generation.
