The marine habitat are sound for the survival of the marine aquatic and marine species such as plants and animals. The open oceans have photic zon e which receives maximum sunlight. This zone is suitable for the survival of marine plants as the availability of sunlight supports photosynthesis. The healthy plants can support the survival of the marine animal species.
In the open ocean, photosynthetic algae using energy from sunlight for photosynthesis. This ensures a rich population of producers in the open ocean to support the life of aquatic organisms in the open ocean.
Summarily, the open ocean supports a wide variety of organisms hence it is the the most productive marine habitat.
