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

原生生便可辨识出烯发送者。

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

如果是它可摄种，它就会直接冲向细菌。

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，如细菌、真菌、原生生和古细菌。

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

根据检测到特定学质，原生生可以识别合种。

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

如果它是原生生吃种，它可以直奔细菌。

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， 但也会使用这些学质中一些来促进它们新陈代谢，并将它们废循环回去以帮助养活原生生。

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.

在每一天过程中， 水母都会迁移以跟随阳光，因此原生生可以进行光合作用并制造大量含能分子。
