Answer :
Final answer:
Photosynthetic organisms in the ocean are found in the photic zone, including the intertidal and neritic zones, where sunlight penetrates, and conditions are favorable for photosynthesis. The correct option for where you'd find these organisms is option b.
Explanation:
Photosynthetic organisms are typically found in areas of the ocean where sunlight can penetrate, allowing for the process of photosynthesis to occur. These areas are in the photic zone, which is the uppermost layer of the ocean where sunlight reaches and includes the intertidal zone and neritic zone. The intertidal zone is between high and low tide, where organisms are adapted to periods of dryness and the pounding of waves, while the neritic zone extends from the intertidal zone to about 200 m depth, is well-oxygenated, and supports a rich variety of sea life due to its conditions favorable for photosynthesis.
Given the information, the regions you would expect to find photosynthetic organisms would be the photic zone, intertidal zone, neritic zone, and the oceanic zone. Therefore, the correct answer to the question In which of the following regions would you expect to find photosynthetic organisms? is option b. The photic zone, the intertidal zone, the neritic zone, and the oceanic zone are areas where enough sunlight is available for photosynthesis to sustain plant life and those photosynthetic organisms necessary for the marine food web.
