If eutrophication is severe the water body may no longer be able to support life. Explain why that is:

Answer 1

Severe eutrophication can lead to a lack of oxygen in the water, a condition known as hypoxia or anoxia. This lack of oxygen can result from the excessive growth of algae and other aquatic plants, which consume oxygen as they decompose. Without enough oxygen in the water, fish and other aquatic animals may suffocate and die. Additionally, the decay of excess plant material can lead to the release of toxic substances and further degrade water quality. Ultimately, severe eutrophication can disrupt the entire aquatic ecosystem, leading to the collapse of food chains and the loss of biodiversity.
