All living things on the earth need other living things to live with. Nothing lives  1 . Sometimes one living thing kills    2  . Each kind of life eats another kind of life     3   live, and together they form a food chain(食物链). Some food chains are simple, while others are not. But    4    food chains begin with the sun, and all food chains become    5   if one of the links disappears.

Meat-eating animals are only   8 plants indirectly.

What about human beings? We are members of many food chains. We eat wheat, rice, vegetables, fruits and so on. We also eat meat and drink milk. But   9     often break up the food chains.

If people eat the fish, they will get strange diseases.

Each form of life is linked to all the others. Breaking the links puts all life in danger.
