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.

Explanation:
Fossil fuels are the fuels which are generated after a long time taking geological process over the buried organic matter obtain from dead animals, animal dung and plants. The organic matter remain under the heap of earth crust under intense heat and pressure. The heat and pressure generate fuels which are valuable for the entire society as when they are burned they produce huge amount of thermal energy. These includes the crude oil like petroleum, natural gas and coal.
