Which of the following is a consequence of increased water temperature due to climate change?

Increased water temperature as a result of climate change significantly impacts aquatic ecosystems, and one of the most notable consequences is increased algae growth. Warmer temperatures create an environment that is more conducive to the proliferation of algae, particularly harmful algal blooms. These blooms occur when nutrient-rich waters, often supplemented by runoff containing fertilizers, allow algae to multiply rapidly.

This increased algae growth can lead to several negative effects on water quality and aquatic life. For example, excessive algae can block sunlight from reaching other aquatic plants, disrupting photosynthesis and leading to a decline in plant life. Additionally, when the algae die and decompose, it can deplete oxygen levels in the water, resulting in hypoxic conditions that are harmful or fatal to fish and other aquatic organisms.

Furthermore, some types of algae produce toxins that can be detrimental to wildlife and pose serious health risks to humans who rely on affected water supplies. Thus, the link between increased water temperature and heightened algae growth is a critical concern in the context of climate change and has far-reaching implications for managing water resources and protecting aquatic ecosystems.
