All living things on the Earth need other living things to live with.Nothing lives alone.Sometimes one living thing kills another.Each kind of life eats another kind of life to live,and together they form a food chain.Some food chains are simple,while other are not.But all food chains begin with the sun,and all food chains become broken if one of the links disappears.
All life needs sunlight to live on.But only plants can use sunlight directly.They make food from sunlight ,water,air ang so on.Animals can only use the sun's energy after it has been changed into food by plants.Some animals feed directly on plants.Others eat small animals.Meat-eating animals are only eating plants indirectly.
What about human begins.We are members of many food chains.We eat plants and animals .But we often break up the food chains.We kill wild animals .We also make rivers ,lakes and seas polluted.In future,we would have no food or drinks.Breaking the links puts all life in danger.
