    As we know, all living things have to eat food. For a man, a tiger, a fish, a bird, or even a worm, food is {#blank#}1{#/blank#} (必需的). Generally speaking, all living things are sure to {#blank#}2{#/blank#} (死) without food. In every part of the world, many different kinds of animals share living places and live in communities (群落) {#blank#}3{#/blank#} (一起). They are connected in a food chain(链).

    Within a food chain， some living things are producers and some are consumers (消费者). Plants are producers because they use {#blank#}4{#/blank#}(阳光)，soil and other things to make their own food. Animals are consumers because they have to eat other animals or plants.

    There are four{#blank#}5{#/blank#} (不同的) kinds of consumers in the animal kingdom. A carnivore is an animal that only eats flesh(肉). A herbivore is an animal that only eats plants. An omnivore is an animal that eats {#blank#}6{#/blank#} (都) meat and plants. A scavenger is an animal that eats dead animals.

    Look at the picture. It is an {#blank#}7{#/blank#} (例子) of a food chain. The food chain {#blank#}8{#/blank#}(显示) the order that animals eat each other in a community. In the picture, you can see what animal or plant is food for {#blank#}9{#/blank#} (另一个) animal. See? A leaf is food for a grasshopper, which then becomes food for a hungry mouse. The mouse is food for a snake. The snake is eaten by an eagle. {#blank#}10{#/blank#} (用) this way, all of these living things are connected.
