If it's a species the protist eats, it can make a beeline straight for the bacteria.

如果是摄食的物种，就会直接冲向细菌。

A teaspoon of soil holds billions of organisms, things like bacteria, fungi, protists and archaea.

一茶匙土壤中含有数十亿种生物，例如细菌、真菌、原生生物和古细菌。

Based on the specific chemicals detected, the protist can identify the terpene sender’s species.

根据检测到的具化学物质，原生生物识别出萜烯发送者的种类。

If it’s a species the protist eats, it can make a beeline straight for the bacteria.

如果这是一种原生生物会吃的物种，直接朝细菌飞去。

Mixotrica paradoxa, one of those fibre-digesting components, is itself a composite of a protist, a single-celled eukaryote, and four types of bacteria.

混养纤维消化成分之一的Mixotrica paradoxa本身是由一种原生生物（单细胞真核生物）和四种细菌组成的复。

Over the course of each day, the jellyfish migrate to follow the sunlight, so the protists can photosynthesize and make lots of energy-containing molecules.

在每一天的过程中， 水母都会迁移跟随阳光，因此原生生物进行光作用并制造大量含能分子。

The jellyfish sometimes hunt, but also use some of these chemicals to fuel their metabolism, and their waste cycles back to help feed the protists.

水母有时会捕食， 但也会使用这些化学物质中的一些来促进们的新陈代谢，并将们的废物循环回去帮助养活原生生物。

That adds in the archaean, bacterial, fungal and protist cells which occupy the mouth, gut, skin, lungs and almost every other surface, nook and cranny of the human body.

这包括了占据人口腔、肠道、皮肤、肺部及几乎每一个表面、角落和缝隙的古菌细胞、细菌细胞、真菌细胞和原生生物细胞。
