Trace the open ocean microbial loop, starting with DOM released by unicells, and follow how it is reprocessed through the bodies of various microorganisms, finally leading up in the bodies of zooplankton
What will be an ideal response?
Single cell organisms are inherently leaky. They and other organisms release dissolved organic matter (DOM) into the water. Heterotrophic bacteria are capable of absorbing this material; acting as recyclers, the bacteria are then consumed by heterotrophic nanoflagellates. The flagellates are consumed by tintinnids and other ciliates. The DOM has now been reprocessed and packaged into organisms that can be consumed by the zooplankton.
