Which organism must live in the photic zone of the ocean biome to perform photosynthesis?

C
Sea Cucumber
D
Phytoplankton
Verified step by step guidance1
Understand the concept of the photic zone: The photic zone is the upper layer of a body of water that receives enough sunlight for photosynthesis to occur. This is where most photosynthetic organisms, like phytoplankton, are found.
Identify the process of photosynthesis: Photosynthesis is the process by which certain organisms convert light energy, usually from the sun, into chemical energy in the form of glucose. This process requires sunlight, which is available in the photic zone.
Recognize the types of organisms that perform photosynthesis: In aquatic environments, the primary photosynthetic organisms are phytoplankton, which are microscopic plants and algae that float in the water column.
Differentiate between the organisms listed: Anglerfish, Giant Squid, and Sea Cucumber are not photosynthetic organisms. They are heterotrophs, meaning they obtain their energy by consuming other organisms.
Conclude that phytoplankton must live in the photic zone to perform photosynthesis, as they require sunlight to produce energy through this process.
