Answer:
D) It would contain less nitrogen.
Explanation:
In an investigation of the cycling of environmental gases, a student placed water and bromthymol blue in each of four test tubes as shown in the diagrams below. No additional items were placed in tube 1, a snail was placed in tube 2, an aquatic plant (elodea) was placed in tube 3, and both a snail and an elodea were placed in tube 4. The tubes were then stoppered and placed in bright light for 24 hours. The solution in tube 3 changes after 24 hours because it would contain less nitrogen.
The dfferent tubes are shown in the picture that I uploaded.

Ans. False.
Coral reefs can be defined as underwater ecosystems, characterized by coral (marine invertebrates) skeletons. Coral reefs can survive only in clean and clear water. Pollutants and sediments smother the coral reefs, reduce water quality, and enhance the growth of damaging algae.
Pollution also makes coral reefs to become susceptible for disease, which impede growth and reproduction of corals, and cause damage to coral reefs.
Thus, the given statement is false as coral reefs are affected by pollution.
