Lack of oxygen in ponds can be caused by several factors, including excessive organic matter decomposition, which consumes oxygen as bacteria break down dead plants and animals. Eutrophication, often due to nutrient runoff from fertilizers, can lead to algal blooms that block sunlight and disrupt photosynthesis. Additionally, warm water holds less oxygen, and stagnant areas of the pond can further reduce oxygen levels. These conditions can lead to hypoxia, negatively impacting aquatic life.
