The source of energy shown in the image is (renewable, non renewable, polluting) a drawback of building a dam is that (it will destroy ecosystems, it requires fossil fuels, it won’t be useful for irrigation)

First blank: renewable

Second blank: destroy ecosystems

Explanation:

Dams are man-made structures that are used to store water for multiple purposes like irrigation, supplying water to an area and power generation. They are also used as a flood control measure.

However, as it is a man-made structure, it can also alter natural habitats and ecosystems. Dams collect water, which means it floods a large area, destroying the ecosystem that used to exist. Also, dams also disturb the natural flow of the river, which many animals and plants rely on. This can be harmful to them.

in a chemical reaction, the atoms and molecules produced by the reaction are called products. no new atoms are created, and no atoms are destroyed. in a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
