Description:

Heterotrophic protists are ubiquitous in all aquatic ecosystems and represent an important ecological link in food webs by transferring organic carbon from primary producers to higher trophic levels. Here, we quantify the predator–prey trophic interaction among protistan grazers and microbial prey within hydrothermal vent fluids from the Gorda Ridge spreading center in the northeast Pacific Ocean.
