Answer :
Final answer:
Phytoplankton are found in the photic zone of the ocean, which is the uppermost layer where sunlight can penetrate. They can produce their own food through photosynthesis. Therefore, the correct answer is : (c).
Explanation:
Phytoplankton are photosynthetic organisms that live in the photic zone of the ocean.
This is the uppermost layer of the ocean where sunlight can penetrate, allowing for photosynthesis to occur. The photic zone extends from the surface down to about 200 meters deep.
Due to the availability of sunlight, phytoplankton can produce their own food through photosynthesis, which is an important source of energy for marine ecosystems.
