Sun

We are learning about ecosystems In an ecosystem there must be these components: atmosphere, heat, light, growing substrate, water, and organisms

Today you will read about the Sun The Sun is the primary source of **heat** and **light** for Earth’s living organisms. • The Sun is part of our Solar System, which is made up of our planet, Earth, and seven other planets that orbit around the Sun. • The Sun is a star and is closer to Earth than any other star. This is why it looks bigger and brighter than other stars even though there are stars that are bigger and brighter than the Sun. • The Sun is made up of burning gases. It is about 92% hydrogen and 8% helium. • The Sun is affected by a lot of pressure because gravity pulls the weight of the Sun in. The pressure causes different kinds of light and waves to come from the Sun. Energy from the Sun heats the Earth.
