Like in the tallgrass prairie ecosystem of the central US, there are over four hundred species of plants at the base of the food web.

就像在美国高草草原生态系统，有超过 400 种植物处于物网底。

In these regions, the eastern parts receive more rain and are naturally tallgrass prairies which blend into the temperate forests of the eastern part of that continent.

在这些地，地降雨较多，是天然高草草原，与该大陆温带森林融为一体。
