This aquatic ecosystem may include protists and bacteria as producers in a well-lit zone and detritus feeders in a deeper dark zone.

Question

Quizplus · Accepted Answer

Lakes have well-lit zones near the surface where photosynthetic protists and bacteria can produce organic matter. In the deeper zones, detritus feeders such as certain species of fish, amphipods, and crustaceans feed on dead organic matter that sinks from the surface. Estuaries, streams, and coral reefs can also have producers and detritus feeders, but hydrothermal vents are typically dominated by chemosynthetic bacteria rather than protists and do not have a well-lit zone.
