Explanation:
Fracking is the introduction of substances into a formation in order to increase they pore pressure and to increase natural drive of hydrocarbons.
Fracking has several environmental issues associated with it;
- Fracking leads to air pollution in case of blowout of gas pressure in formations, particles and dusts can become blasted into the environment.
- Proppants in fluids channeled into formations can lead to ground water contamination.
- In areas where fracking is done, there might be an exposure to harmful chemicals.
- Destruction of the natural habitats of animals.
Answer:
The correct answer is The process of photosynthesis is energy storing because the process converts light energy into chemical energy which stored in the bonds of glucose.
Explanation:
During photosynthesis the light harvesting complexes absorb sunlinght and transfer that light energy to the reaction centre of photosystem.The photosystem then converts the light energy into chemical energy in form of ATP.
The ATP molecules are used along with NADPH to form glucose in the dark reaction of photosynthesis.
