A food web shows how animals and plants are connected together and how they rely on each other for food.

生態網顯示了動物和植物是如何聯繫在一起，以及它們是如何相互依賴以獲取食物的。

Small animals eat plants, and then those small creatures are eaten by bigger creatures.

小動物吃植物，然後這些小動物就會被較大的動物吃掉。

Snails are called detritivores.

蝸牛稱作食碎屑者。

They eat rotten leaves and help the soil by recycling waste and keeping goodness in the ground so that plants and crops can grow.

它們吃爛葉子，並回收廢物，把好東西留在地裡來幫助土壤，讓植物和農作物得以生長。

Snails, in term, provide food for animals like hedgehogs or small birds.

蝸牛則可以當做食物提供給動物，例如刺猬或是小鳥。

Bigger animals like owls, then eat the small birds and hedgehogs.

然後大一點的動物，像是貓頭鷹會吃掉小鳥和刺蝟。

And so the food web continues.

而生態網就這樣持續運作著。

So without animals like snails, there wouldn't be enough food for animals like hedgehogs or even owls.

所以如果沒有蝸牛這種動物，就沒有足夠的食物給刺蝟甚至貓頭鷹這種動物。

They're all part of a large food web.

它們都是一大生態網的一部分。

All the animals in the food web are very important.

生態網中的所有動物都非常重要。

Even the littlest snails, as they all have a part to play in keeping the Earth working as it should.

即使是最小的蝸牛，它們都有責任讓地球保持應有的工作狀態。
