In biology, a scavenger refers to an organism that obtains nutrients by consuming carrion, the remains of dead animals. This ecological role is crucial for nutrient cycling within an ecosystem, as scavengers prevent the accumulation of decaying biomass and accelerate the decomposition process. By feeding on dead matter, they help break down organic materials, returning essential elements such as nitrogen and phosphorus to the environment where they can be utilized by primary producers. This function is vital for maintaining the health and balance of natural habitats.
