The Food Chain

The food chain is when an animal eats an animal and then another animal eats that animal and it keeps on going.

Everything starts from the sun because the suns energy makes grass and plants grow. Then a cow will eat the grass and then we eat the meat from the cow.

This picture gives you an idea of a food chain.

The grasshopper eats the grass and the mice eat the grasshopper and finally the Owls eat the mice.

When part of the food chain gets taken out it can collapse other parts, for example if you take grass away then the grasshoppers die of starvation and then the mice have less to eat. This makes it harder for Owls to find food

This food web picture shows how all the food

chains are linked and if one part disappears, it

can effect everything else.

Sometimes if part of the food chain disappears

then other animals will become too many,

as they haven't got a predator.

This is also bad because they can

have too many numbers and then eat all the

food that other animals need.

The reasons part of the food chain can break down are

1. Humans over hunting
2. Disease causing animals to die
3. Humans destroying where animals live
4. Putting aggressive animals into the wrong areas
5. Pollution of land and the sea.
