Because they are our friends and
they help keep the balance of nature.
1. What is its name
2. Where does it live / grow
3. Why did you choose it
4. What are some interesting facts about it
Its name is sunflower.
It mainly grows in sunny fields, meadows and farmlands in temperate and tropical regions. It needs plenty of sunlight to thrive.
I chose it because its bright yellow petals always face the sun, which gives people a feeling of warmth and vitality. It also symbolizes optimism and positive-ness.
Some interesting facts about sunflowers: First, the head of a sunflower is actually made up of thousands of tiny flowers. Second, sunflowers can track the movement of the sun across the sky during the day, a phenomenon called heliotropism.Third, sunflower seeds are not only a popular snack but also an important source of oil.
