Answer:
D. water is able to hold dissolved oxygen
Explanation:
Dissolved oxygen (DO) can enter water by <em>diffusing</em> across the surface of water from the air, or as a <em>byproduct of photosynthesis</em> by other aquatic organisms like plants and algae. Each aquatic organism, like land-dwellers, has specific oxygen requirements. Fish use DO for the process of respiration, where they obtain oxygen from the surrounding water using their gills. Anoxic conditions, where oxygen levels are low usually result in significant deaths in fish populations.
