The way those nutrients move between organisms and their environment is called a nutrient cycle.

这些营养物质在生物体和环境之间移动的方式被称为营养循环。

Nutrient cycles move in a circle, and plants are one stop on that roundabout route.

营养循环是一个循环，植物是这个迂回路线上的一站。

And on a global scale, plants connect all of these complex biomes through nutrient cycles, or pathways that move nutrients between living organisms and their environment.

在全球范围内，植物通过营养循环或在生物体和环境之间移动营养物质的途径将所有这些复杂的生物群系连接起来。

Thinking beyond human health, bacteria are really important for global nutrient cycles – kind of like the fish pee in coral reefs, but everywhere!

超越人类健康，细菌对全球营养循环非常重要——有点像珊瑚礁中的鱼尿， 但无处不在！
