Which of the following is a consequence of aquatic weed decomposition?

• A. Increased water inflow
• B. Reduction of sediment levels
• C. Filling in of bodies of water
• D. Improved light penetration

Answer: (C)

Filling in of bodies of water is a consequence of aquatic weed decomposition because as plants die and decompose, they contribute organic matter to the sediment at the bottom of the water body. This accumulation of organic matter can lead to the gradual filling of lakes and ponds, a process known as eutrophication. Over time, as more plant material decomposes and is added to the sediment, it can raise the bottom of the body of water, potentially leading to a decrease in its overall depth and size. Decomposing aquatic weeds can also affect the physical and chemical properties of the water, but the most direct consequence related to the filling in of bodies of water involves the addition of organic debris to the sediment. This process underscores the dynamic interactions within aquatic ecosystems, where plant life plays a key role in shaping the physical landscape.
