Question
Mussels live in freshwater environments. How does climate change contribute to the reduction of dissolved oxygen levels in their habitat?
It leads to an influx of oxygen-rich air into the water.
It promotes algal blooms, which consume oxygen during decomposition.
It increases the metabolic activity of mussels, releasing more oxygen.
It increases oxygen production by aquatic plants.

Climate change contributes to the reduction of dissolved oxygen levels in mussels' freshwater habitats primarily through **promoting algal blooms, which consume oxygen during decomposition**.
Rising temperatures and increased nutrient runoff (often due to heavier rainfall and agricultural runoff) can lead to algal blooms. When these algae die and decompose, the decomposition process consumes significant amounts of dissolved oxygen in the water, leading to hypoxic conditions that can be harmful or fatal to aquatic life, including mussels.
The other options listed do not accurately reflect the effects of climate change on dissolved oxygen levels in freshwater environments.
