为什么植物很重要英语作文

英文回答：

Plants are essential for life on Earth. They provide us

with oxygen, food, and shelter. They also play a vital role

in the water cycle and in regulating the Earth's climate.

Oxygen.

Plants are the primary producers of oxygen on Earth.

They use sunlight to convert carbon dioxide and water into

glucose and oxygen. This process, known as photosynthesis,

releases oxygen into the atmosphere. Oxygen is essential

for all life forms, including humans.

Food.

Plants are a major source of food for humans and

animals. We eat the leaves, fruits, seeds, and roots of

plants. Plants also provide us with essential vitamins and

minerals.

Shelter.

Plants provide shelter for humans and animals. Trees

can provide shade from the sun and protection from the rain.

Plants can also be used to build houses and other

structures.

Water cycle.

Plants play a vital role in the water cycle. They

absorb water from the soil and release it into the

atmosphere through transpiration. This process helps to

regulate the Earth's climate and provides water for other

life forms.

Climate regulation.

Plants help to regulate the Earth's climate by

absorbing carbon dioxide and releasing oxygen. Carbon

dioxide is a greenhouse gas that traps heat in the

atmosphere. By absorbing carbon dioxide, plants help to

reduce the amount of heat that is trapped in the atmosphere

and keep the Earth's climate stable.

Conclusion.

Plants are essential for life on Earth. They provide us

with oxygen, food, shelter, and other vital resources. They

also play a vital role in the water cycle and in regulating

the Earth's climate.

中文回答：

植物对于地球上的生命至关重要。它们为我们提供氧气、食物

和住所。它们还在水循环和调节地球气候方面发挥着至关重要的作

用。

氧气。

植物是地球上氧气的主要生产者。它们利用阳光将二氧化碳和

水转化为葡萄糖和氧气。这个过程叫做光合作用，它将氧气释放到

大气中。氧气对于所有生命形式，包括人类，都是必需的。

食物。

植物是人类和动物的主要食物来源。我们食用植物的叶子、果

实、种子和根。植物还为我们提供必需的维生素和矿物质。

住所。

植物为人类和动物提供住所。树木可以遮挡阳光和雨水。植物

还可以用来建造房屋和其他建筑物。

水循环。

植物在水循环中发挥着至关重要的作用。它们从土壤中吸收水

分，并通过蒸腾作用将其释放到大气中。这个过程有助于调节地球

的气候并为其他生命形式提供水。

气候调节。

植物通过吸收二氧化碳和释放氧气来帮助调节地球的气候。二

氧化碳是一种温室气体，它将热量困在大气中。通过吸收二氧化碳，

植物有助于减少困在大气中的热量，并保持地球气候的稳定。

结论。

植物对于地球上的生命至关重要。它们为我们提供氧气、食物、

住所和其他重要资源。它们还在水循环和调节地球气候方面发挥着

至关重要的作用。
