Sunflowers interact with the environment.
They turn their faces toward the sun.

Sunflowers always face the sun to get the most sunlight.

Sunflowers track the sun across the sky.
This activity is known as solar tracking.

Sunflowers track the sun from east to west
and turn back east overnight to await the sun.

The Venus flytrap has trigger hairs on the leaves.
The two lobes of the leaves have blades with spiny teeth.

When anything touches the trigger hairs,
the two lobes of the leaves snap shut trapping whatever is inside.

The trap will shut in less than a second.

Once the trap is closed, digestive acids dissolve the insect.
Then, the plant absorbs the essential nutrients.

Seven to ten days later, the trap reopens, ready for another meal.
