Is the statement "the aging and deterioration of a lake's ecosystem is influenced by nutrient addition" true?

The statement "the aging and deterioration of a lake's ecosystem is influenced by nutrient addition" is accurate. This phenomenon, often referred to as eutrophication, occurs when an excessive amount of nutrients—especially nitrogen and phosphorus—are introduced into a water body. These nutrients can originate from various sources, including agricultural runoff, wastewater discharge, and urban runoff.

As nutrient levels rise, they often lead to increased plant and algae growth. While some level of nutrient presence is necessary for aquatic ecosystems, excessive amounts can result in harmful algal blooms. These blooms can deplete oxygen in the water as they die off and decompose, leading to hypoxic or anoxic conditions that threaten fish and other aquatic organisms. This process can significantly alter the health and composition of the ecosystem, resulting in the deterioration of water quality, biodiversity loss, and overall ecological balance.

Therefore, nutrient addition plays a pivotal role in the aging and degradation of a lake's ecosystem, contributing to long-term changes that can have serious ecological consequences.
