Hey mom, how does the food chain work?
Well lets start from the beginning.
First, plants make there food from sunlight, water, and carbon dioxide. These plants are producers.
No, all plants are producers.
So, just this type of plant is a producer?
A primary consumer is an animal, such as a grasshopper, that eats producers. It is the first consumer in the food chain. Now continuing on now 10% of the plants energy is passed to the grasshopper.
As the plant keeps growing, primary consumers start to eat them.
Whats a primary consumer?
 As I was saying, now 10% of the energy from the grasshopper is passed on to the mouse. This mouse is also known as a secondary consumer.
Now lets say that a mouse comes along and eats the grasshopper. Now...
Because if grasshoppers did not get eaten then mice would starve and die.
But mom, why does the grasshopper have to die?
That's right. This is also a secondary consumer.
As our little mouse walks through the forest a snake comes up and eats it. Now...
No, you can have more than one secondary consumer.
Wait, I thought you could only have one secondary consumer.
10% of the energy is passed on to the snake!
As this snake slithers through the forest, a bald eagle comes out of nowhere and grabs the snake with its talons. 
A tertiary consumer is the highest level of the food chain.
Yes, and the bald eagle is a tertiary consumer.
And 10% of the energy gets passed on to the eagle.
