Scavengers play a vital role in ecosystems by consuming dead and decaying organic matter, including carcasses and plant debris. By breaking down this material, scavengers help in the process of nutrient cycling, returning essential nutrients to the soil and promoting plant growth. Scavengers also help control the spread of disease by consuming remains that could harbor pathogens. This cleanup role contributes to overall ecosystem health and stability, ensuring that energy and nutrients are efficiently recycled.
