A food chain shows the order in which animals eat plants and other animals.

At the bottom of the food chain are plants. The sun gives plants energy.

Animals that eat plants are the next link. We call them plant eaters, such as insects.

Animals that eat other animals are the third link. We call them meat eaters, such as mice, snakes and hawks.

Animals that are not hunted by other animals are at the top of the food chain, just like human beings.

食物链显示了动物吃植物或者其他动物的顺序。

在食物链最底层的是植物。太阳给植物能量。

吃植物的动物在下一环节。我们管它们叫食草者，例如昆虫。

吃其它动物的动物在第三环节。我们管它们叫食肉者，例如老鼠、蛇和鹰。

不被其它动物狩猎的动物在食物链最顶层，就像人类一样。
