A forest is like a football group. It sounds unusual, but it’s true. Each player does an important job, but they can’t win by themselves, so they work together. The same is true of all plants and animals in a forest. They depend on each other to live. We call this an ecosystem.
There are three jobs in an ecosystem: producer, consumer and decomposer. The trees in the forest produce food by themselves. Giraffes themselves can’t make their own food, so they consume or eat the trees’ leaves. But sometimes hungry lions or other animals eat giraffes. When animals die, their bodies become part of the soil(土壤) and air to help the forest grow. So the ecosystem can keep on going.
Ecosystems come in lots of kinds and sizes. A backyard or even a big sea can be an ecosystem. The key thing is that an ecosystem has to be balanced. If there weren’t animals to eat giraffes, giraffes would eat too many leaves. This wouldn’t be good for the trees, and this would make it difficult for giraffes to find food. Different weather and natural disasters can change the ecosystems. Human activities like cutting down trees and hunting can also bring problems.
Ecosystems are everywhere. They play an important part in our life. It is necessary for us to do what we can to keep them working well.

一片森林就像一支足球队。这听起来很不寻常，但却是真的。每个球员都承担着重要的任务，但他们无法独自获胜，所以他们会共同协作。森林里的所有动植物也是如此。它们相互依存以求生存。我们把这称为生态系统。
生态系统中有三种角色：生产者、消费者和分解者。森林里的树木自己生产食物。长颈鹿自身无法制造食物，所以它们会食用树木的叶子。但有时饥饿的狮子或其他动物会捕食长颈鹿。当动物死亡时，它们的身体会成为土壤和空气的一部分，以帮助森林生长。这样生态系统就能持续运转。
生态系统有很多种类和规模。一个后院甚至一片大海都可以是一个生态系统。关键在于生态系统必须保持平衡。如果没有动物捕食长颈鹿，长颈鹿就会吃掉太多树叶。这对树木不利，也会让长颈鹿难以找到食物。不同的天气和自然灾害会改变生态系统。像砍伐树木和狩猎这样的人类活动也会带来问题。
生态系统无处不在。它们在我们的生活中起着重要作用。我们有必要尽我们所能来保持它们的良好运转。
