Pond accumulation is the process of collecting organic matter, such as ALGAE, in a body of water. ALGAE is a type of plant-like organism that can be found in both freshwater and saltwater environments. It is an important part of the food chain, providing food for fish and other aquatic life. ALGAE also helps to keep the water clean by absorbing nutrients and pollutants. Pond accumulation is a natural process that helps to maintain the balance of the ecosystem.
