The primary diet of a scavenger consists of dead animals and organic refuse. Scavengers play a vital ecological role by consuming carrion, which helps to recycle nutrients back into the ecosystem and prevent the spread of disease. Common scavengers include vultures, hyenas, and certain species of crabs, which have adapted to efficiently locate and process decaying matter. Their digestive systems are often equipped with specialized enzymes that enable them to break down tough tissues. By feeding on remains, scavengers contribute to the overall health of their habitats and maintain ecological balance.
