Question

State whether the following statements are true or false.

6. ${\mathrm{CO}}_2$ can be used to preserve food grains from destruction by insects.

• A. True
• B. False

Answer 1

The correct option is A True

• Nowadays Carbon dioxide $\left({\mathrm{CO}}_2\right)$ is being used to prevent the grain from destruction by insects.
• When food grains are kept in the atmosphere of Carbon dioxide, it reduces the respiratory rate of the insect.
• Hence, it becomes difficult for insects to survive.
• Controlled atmosphere storage is a process that utilizes ${\mathrm{CO}}_2$ for the preservation of food grains and is preferred over the use of insecticides and pesticides.

Thus, the given statement is true.
