C
Benthic zone
D
Abyssal zone
Verified step by step guidance1
Understand the concept of photosynthesis: Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll pigments. It primarily occurs in regions where sunlight is available.
Identify the regions of the ocean biome: The ocean biome is divided into different zones based on light penetration and depth. These include the photic zone, aphotic zone, benthic zone, and abyssal zone.
Define the photic zone: The photic zone is the uppermost layer of the ocean that receives sunlight. It typically extends to a depth of about 200 meters, where enough light penetrates to allow photosynthesis.
Contrast with the aphotic zone: The aphotic zone lies below the photic zone and receives little to no sunlight, making photosynthesis impossible in this region.
Conclude which zone supports photosynthesis: Since photosynthesis requires sunlight, the photic zone is the region of the ocean biome most likely to have the highest rate of photosynthesis due to its exposure to sunlight.
