a way that some living things make their own food by getting energy from chemical reactions in substances such as hydrogen sulfide, instead of relying on sunlight.

例句

Giant tube worms at hydrothermal vents depend on chemosynthesis performed by bacteria inside their bodies.

棲息於深海熱泉的巨型管蟲依賴體內細菌進行的化學合成來獲取能量。

Unlike green plants, the bacteria living in deep-sea sediments use chemosynthesis to produce energy from sulfur compounds.

與綠色植物不同，生活在深海沉積物中的細菌利用硫化物進行化學合成以產生能量。

用法筆記

This uncountable noun is almost always used in academic or scientific writing about deep-sea ecology. The opposite process, which uses sunlight, is photosynthesis.

常見錯誤

❌Plants use chemosynthesis to make food from sunlight.
✅Plants use photosynthesis to make food from sunlight, while deep-sea bacteria rely on chemosynthesis.
💡chemosynthesis uses chemical energy, not sunlight; the plant process is photosynthesis.
