Which statement correctly explains how marine garbage impacts biodiversity in a marine ecosystem?

a.) animals use it as nesting material and it is toxic to their young.
b.) as the plastic biodegrades, it produces chemicals that can increase reproduction rates.
c.) it is often mistaken as floating food and is harmful after being ingested.
d.) many organisms fear the floating plastic, so they migrate to other areas.

C.) It is often mistaken as floating food and is harmful after being ingested.

Explanation:

The floating plastic in the marine garbage can impact the biodiversity in a marine ecosystem. As, the plastics may be eaten along with the food by the marine animals. Plastic being a non-biodegradable material will remain undegraded in the marine water body as well as in the digestive system of the marine animals. Hence, will result in mortality of the marine animals. This will lead to decline in biodiversity of the marine ecosystem.    

explanation:

on disadvantage of hydroelectric power is the cost. another disadvantage of using hydroelectric power is finding a water source powerful enough to harvest hydroelectric power.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
