<span>A food preservation method in which microorganisms metabolize components of a food is called </span>fermentation.
When the food is going on fermentation, there are good bacteria over there that will inhibit other bacteria to grow on that food. Fermentation also able to made the pH more acid, making the area is not suitable for bacterial growth.

The correct answer is C. To store gastroliths that physically grind up food.
Explanation
The gizzards, are a special part of the digestive system of some animals such as birds, fish, and reptiles whose main function is to crush the food that the animal ingests, for this task, the gizzards contain in their interior gastroliths, a kind of polished stones, that grinds the food that the animal eats.

Chemical weathering by carbonation
Explanation:
Chemical weathering by the process of carbonation will cause the inscription on a marble gravestone to become more difficult to read with time. 
Chemical weathering is the decomposition and decay of rocks to form sediments and soil. 
- Marble is metamorphic carbonate rock. 
- It is derived from the metamorphism of limestone and dolomitic rocks.
- In the presence of weak carbonic acid, it becomes soluble
- Carbonic acid is formed when atmospheric carbon dioxide combines with rain water. 
- The carbonic acid dissolves the marble and washes it away in solution.
