地球上每年都要死亡大量动植物,千万年过去了,这些动植物的遗体到哪里去了呢?其实是被分解掉了,是被什么分解了呢?其实,在大自然中,生活着一大类人的肉眼不易看见的微小生命。动植物遗体被分解就是这些微小生命的功劳。它们能把地球上一切生物的残躯遗体“吃”个精光,同时转化成植物能够利用的养料,为促进自然界的物质循环立下了汗马功劳。因此无论是繁华的现代城市、富饶的广阔田野、还是人迹罕见的高山之巅、辽阔的海洋深处,到处都有它们的踪迹。这一大类微小的“居民”称为微生物,它们和动物、植物共同组成生物大军,使大自然显得生机勃勃。 Thousands of years have passed since the end of this year. How many animals and plants have died on Earth every year? Where are the remains of these animals and plants? In fact, they have been decomposed and are decomposed? In fact, in nature, A large group of people’s naked eye is not easy to see the tiny life. The decomposition of animal and plant remains is the merit of these tiny lives. They can “eat” the remains of all creatures on the earth and at the same time turn them into nutrients that can be used by plants, thus contributing to the promotion of material circulation in nature. Therefore, no matter it is a prosperous modern city, a vast expanse of fertile land, or a top of a mountain that is rare on earth, the vast depths of the sea have their traces everywhere. The tiny “residents” of this large group are called microbes, and they form a large army of creatures with animals and plants to make nature appear vibrant.
