In which of the following regions would you expect to find photosynthetic organisms?

• A. Abyssal zone, benthic zone, & neritic zone.
• B. Intertidal zone, benthic zone, & neritic zone.
• C. Intertidal zone, photic zone, & neritic zone.
• D. Littoral zone, aphotic zone, & intertidal zone.

Answer: (C)

Verified step by step guidance

1. Understand that photosynthetic organisms require light to perform photosynthesis, so they are typically found in regions where sunlight can penetrate.
2. Identify the zones mentioned in the problem: abyssal zone, benthic zone, neritic zone, intertidal zone, photic zone, and aphotic zone.
3. Recognize that the photic zone is the upper layer of water that receives enough sunlight for photosynthesis, making it a suitable environment for photosynthetic organisms.
4. Consider the intertidal zone, which is the area between high and low tide marks. This zone is exposed to sunlight during low tide, allowing photosynthetic organisms to thrive.
5. Note that the neritic zone is the shallow part of the ocean above the drop-off of the continental shelf, which is well-lit and supports photosynthetic life. Therefore, the correct regions are the intertidal zone, photic zone, and neritic zone.
