Answer the following question given this paragraph: Only the top 200 meters or so of water receive enough sunlight for photosynthesis. This part of the water is called the photic zone. Below 200 meters, there is too little sunlight for photosynthesis to take place. This part of the water is called the aphotic zone. In this zone, food must come from other sources. It may be made by chemosynthesis, in which microorganisms use energy in chemicals instead of sunlight to make food. Or, food may drift down from the water above. Q: What is the top part of water able to receive enough sunlight for photosynthesis called? Choices: - thymic zone - synthesis zone - fantasmic zone - photic zone A:
(A).
photic zone
