Final answer:
When algae grows with all the nitrogen, it can result in overgrowths called algal blooms. These blooms can lead to depleted oxygen levels, changes in pH, and harm to fish and other aquatic animals.
Step-by-step explanation:
When algae grows with all the nitrogen, it can result in overgrowths of algae called algal blooms. These blooms can lead to the depletion of oxygen in the water, causing harm to fish and other aquatic animals. The pH of the water can also change, affecting metabolic processes.
Eutrophication is an example of how excess nitrogen and phosphorus in bodies of water can cause the overgrowth of algae. This overgrowth can clog waterways, block sunlight to deeper levels, and deplete dissolved oxygen, ultimately harming other aquatic organisms and disrupting the ecosystem.
Therefore, the habitat can be negatively impacted by algal blooms, resulting in changes to the oxygen levels, pH, and overall health of the ecosystem.
