章節(jié)摘錄

　　All living things on the earth need other livingthings to live. Nothing lives alone. Most animals mustlive in a group，and even a plant grows close togetherwith others of the same kind. Sometimes one livingthing kills another， one eats and the other is eaten.Each kind of life eats another kind of life in order tolive，and together they form a food chain .Some food chains are simple， while others are not.But all food chains begin with the sun， and all foodchains become broken up if one of the links disap-pears.　　All life needs sunlight to live on. But only plantscan use sunlight directly. Plants are "factories". Theymake food from sunlight， water and things in the soiland air.　　Plants feed all other living things. Animals canonly use the suns energy after it has beenchanged into food by plants. Some animals feed di-rectly on plants， others eat smaller animals. Meat-eat-ing animals are only eating plants indirectly.　　What about human beings？ We are members ofmany food chains. We eat wheat， rice， vegetables， fruits and so on. We also eat meat and drink milk. But men often break up the food chains. They kill wild animals. They also make rivers， lakes and seas dirty.When these rivers， lakes and seas are polluted， thefish in them cant be eaten. If men eat the fish， theywill get strange diseases.　　Each form of life is linked to all others. Breakingthe links puts all life in danger.
