The Effect On Earth

A solar eclipse occurs when the Moon passes between Earth and the Sun during its journey around Earth.

When a solar eclipse occurs, strange things sometimes happen on Earth. At mid-day, the sky appears to be darkened. Animals such as birds are sometimes tricked into thinking that it is night time, and so they go to sleep!

What would happen to life on Earth if the Sun suddenly disappeared?

All living things must eat or manufacture food to stay alive. Where does that food come from? For almost all organisms on the planet, food comes from the Sun, either directly or indirectly. There are two basic ways that living things get their energy from the Sun. Plants and algae produce their own food by a process known as photosynthesis. During photosynthesis, chlorophyll, the pigment that makes plants green, converts the Sun's light into food for plants so that they can grow. Humans and other animals eat plants to get energy to stay alive. Even when humans eat animal flesh (meat) such as beef, they are consuming part of an animal that ate plants in order to grow and stay alive.

Organisms that make their own food are called PRODUCERS because they produce food for the rest of the organisms on the planet. Examples are plants, algae, and certain types of bacteria known as blue-green bacteria.


Organisms that eat producers (and only producers) are called first order consumers.
Organisms that eat producers and first order consumers are called second order consumers.

To the consumers? Why?
