Answer:

Our body need energy when we are tired

Answer 2

$\huge\underline\blue{Answer:-}$

The body needs energy for everything it does: breathing, eating, sleeping, walking, working and any other activity that we perform in our daily life.

Despite the fact that you are resting, your body still consumes energy when you sleep. Energy use is particularly high during REM (rapid eye movement) sleep. During this time, your brain is highly active and you burn the most glucose, your body's source of fuel.
