Which contains more oxygen?

• Warm water

Why is the warm water released from power plants an issue for the organisms that live in that water?

• The warm water provides a comfortable environment for the organisms to thrive
• The warm water helps regulate the ecosystem by maintaining a stable temperature
• The warm water can disrupt the natural ecosystem by increasing the water temperature, which can negatively impact the organisms adapted to a specific temperature range.
• The warm water promotes biodiversity among the organisms
