The primary role of wastes in ecosystems is as a source of nutrients that support the nutrient cycle. Organic waste, such as decomposing plants and animal matter, provides essential nutrients for soil health, promoting the growth of vegetation. Microorganisms play a crucial role in breaking down waste, recycling it back into the ecosystem. However, the accumulation of pollutants and plastic waste can disrupt this process and lead to negative environmental impacts, highlighting the importance of waste management in maintaining ecological balance.
