Listen to the song. Can you answer the question?

Sunflower in the sun
Sunflower in the sun, growing very high.
Sunflower in the sun, growing very high.
Sun and water you need to make you grow from a seed.
Till you look like a yellow sun.
Till you look like a yellow sun.

A sunflower grows taller and taller
Till you can’t touch its head with your hand.
A sunflower grows bigger and bigger.
It’s proud, it’s yellow, it’s grand.

A giant sunflower is enormous.
It’s an incredible height.
I know that sunflowers love the sun,
But what do they do at night?
Please tell me, what do they do at night?
