The Food Chain
Текст на Статията
- 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.
