水係生物必要既野??

這是因為生物大多是水做的。人類和其他動物用的水分解葡萄糖，而葡萄糖轉化為能量。水有能力控制溫度。這意味著當周圍是熱的，水從周圍吸收熱量（如蒸發。當周圍是冷，它會釋放出能量。這樣的溫度控制讓水在我們的身體在廣泛的溫度範圍維持流體。讓我們的身體正常工作，因為我們的身體中的酶(enzyme)工程，在特定的溫度範圍。流體在你的身體也讓器官之間有空間。它可以保護你。例如，如果你撞頭了，水有助於吸收一些衝擊。但是，當然你的頭骨，是主要的保護元件。(水仍然有很多的好處和用法，如果您需要更多信息，請做更多的研究。)

像古細菌 (Archaea) 能生活在其他礦物，並不需要氧氣 (像那些在熱液噴口(hydrothermal vent) 附近生活的)。Archaea 可以生活在世界上最極端的條件和環境的地方。古細菌是單細胞微生物，就像細菌。然而，他們有一個更簡單的組成，並比細菌通過向更高了進化鏈。除了古菌，也有一些孢子仍然是可行的，可以存儲在多年後沒有水的環境中。但它仍然不能永遠存放在乾燥的環境中。科學家說，微生物可以生活在太空和流星，但我不知道這些微生物的生活方式。

以上是翻譯我的原詞如下。所有的信息是從我的記憶中，如果有什麼是不正確的，我道歉。

It is because organisms are mostly made of water. Human and other animal use water to break down glucose, which is converted to energy. Water has the ability to control temperature. That means it absorb energy when it is hot and release energy when it is cold. Such temperature control allow water to remind fluid in our body through wide ranges of temperature. And allow our body to function properly since enzymes in our body works in a specific temperature range. The fluid component in your body also allow space between organs. It can work as protection in come cases. For example, if you hit your head, the water help absorb some of the shock. But of course your skulk is the one that is the main protecting component. (Water still have a lot of benefit and usage, if you need more information please do more research.)

There are organisms like the archaea that can live on other mineral and does not require oxygen (like those living around hydrothermal vent). Some archaea can live in the world's most extreme condition and environment. Archaea are single cell organism much like bacteria. However, they have a even less complex made up and is through to be higher up the evolutionary chain than bacteria. Besides from Archaea, there are some spores that can still be viable after being store in an environment without water for many years. Scientists say that microorganism can live in space and in meteoroid, but I don't know how those organism lives.

事實上係有生物唔需要氧，
如一啲細菌，
冇啲生物喺有氧嘅時候進行需氧呼吸，
無氧時進行缺氧呼吸。

P.S. 水是生物體很多化學反應、運輸物質的媒介，
因此水是必需的。
