植物没有脚,却也能不断地迁移,从一个地方来到另一个地方,继续繁衍着自己的后代。这类大“搬家”有时依靠大自然的力量,如蒲公英的种子外面包裹了一层絮毛,靠着这小小的“降落伞”,它可以漂浮在空中被风送到远处; 有时借助动物的携带,如有些植物的果实被鸟儿吞食后,未被消化的种子会被飞鸟带往远方,然后随鸟粪一起排出,散落各处; 有时则是被人带到新的家园,如仙人掌、风信子、水葫芦等植物就是如此。植物来到新的地方,它们的命运会怎样呢?它们的兴衰会对当地的生态产生怎样的影响呢? Plants without feet, but also can continue to migrate, from one place to another place, continue to multiply their own offspring. Such big “movers” sometimes rely on the power of nature, such as dandelion seeds covered with a layer of silky hair, relying on this little “parachute”, it can float in the air was sent to the wind; and sometimes with animals If some of the fruits of a plant are swallowed by birds, the undigested seeds are taken away by the birds and then expelled together with the bird droppings, scattered throughout; sometimes they are taken to new homes, such as cacti , Hyacinth, water hyacinth and other plants is so. Plants come to a new place, their fate will be what? Their rise and fall of the local ecology will have what kind of impact?
