Answer :
The zonephotic, the sunlit region of the ocean, is the primary habitat for phytoplankton. Option (c.) zonephotic is the Right Choice.
Here's why:
- Intertidal: This zone is the area between the high and low tide marks, and while some phytoplankton can be found here, it's not their primary habitat.
- Zona/zonephotic: This is the upper layer of the ocean where sunlight penetrates sufficiently for photosynthesis. This is where the vast majority of phytoplankton are found.
- Zonebenthic: This is the deep ocean floor, which does not receive enough sunlight for photosynthesis and is not suitable for phytoplankton.
- Realm: This term is too broad and encompasses all aquatic environments, not just specific zones within the ocean.
Phytoplankton are primarily found in the zonephotic, also known as the euphotic zone, of the ocean. This region extends from the surface down to the depth where sunlight can penetrate, allowing photosynthesis to occur. Within the zonephotic, phytoplankton flourish near the ocean surface, harnessing sunlight to convert carbon dioxide and nutrients into organic compounds. This process forms the foundation of the marine food web, as phytoplankton serves as a vital food source for various marine organisms.
In conclusion, option (c) zonephotic is the correct choice, as it accurately identifies the oceanic region where phytoplankton predominantly thrive, benefiting marine ecosystems and supporting biodiversity.
