Question

dissolved oxygen
dissolved oxygen levels differ significantly in various aquatic environments, including oceans, rivers, streams, and lakes. factors like the presence of certain chemical pollutants can deplete dissolved amounts of dissolved oxygen, making it essential to monitor water quality. additionally, water temperature plays a crucial role in altering dissolved oxygen levels. climate change poses a notable concern in this regard, as rising temperatures can lead to increased water temperatures in these ecosystems, leading to lower dissolved oxygen levels. such changes can have adverse effects on aquatic life and the overall health of these bodies of water.
what environmental concern related to climate change could result in lower dissolved oxygen levels in water?
warmer water temperatures
decreased water pollution
increasing biodiversity
rising water salinity

Explanation:

Warmer water temperatures due to climate - change reduce the solubility of oxygen in water, leading to lower dissolved oxygen levels. Decreased water pollution would likely increase dissolved oxygen. Increasing biodiversity doesn't directly lower dissolved oxygen. Rising water salinity has a more complex relationship but is not a primary climate - change factor for reducing dissolved oxygen compared to temperature.

Answer:

warmer water temperatures
