Explanation:
Detailed explanation-1: -The colder water is, the more oxygen it can hold. As the water becomes warmer, less oxygen can be dissolved in the water. Salinity is also an important factor in determining the amount of oxygen a body of water can hold; fresh water can absorb more oxygen than salt water.
Detailed explanation-2: -Oxygen from the atmosphere dissolves and mixes into the water’s surface. Algae and underwater grasses release oxygen during photosynthesis. Water flows into the Bay from streams, rivers, and the ocean. Ocean waters generally have more oxygen.
