When you put an ant inside the close jar they can survive?

Ants can survive in a closed jar for a limited time due to their ability to tolerate low oxygen levels and their efficient use of stored energy. They can rely on their fat reserves and can also enter a state of reduced metabolic activity. However, without access to food and water, they will eventually succumb to dehydration and starvation. The duration of their survival depends on factors like the temperature and the size of the jar.
