what are the primary producers out in the open waters?
phytoplankton
zooplankton
bacterioplankton
femtoplankton

Explanation:

• Corals are made up of tiny organisms called polyps. Polyps are the building blocks of individual corals and they can form larger coral colonies. Cnidarian is a phylum that includes polyps (corals are in the phylum Cnidaria). Mesoglea is a jelly - like substance in cnidarians. Reefs are large structures formed by corals (which are made of polyps).
• Phytoplankton are primary producers in open waters. They use photosynthesis to convert sunlight into energy. Zooplankton are consumers (they eat phytoplankton and other small organisms). Bacterioplankton are bacteria in the plankton (they can be decomposers or have other roles). Femtoplankton are very small plankton, but they are not the primary producers.

Answer:

• First question: polyps
• Second question: phytoplankton
