Vultures have many biological adaptations that make them well-suited to being scavengers. Vultures only eat the bodies of dead animals. Scavengers break down this organic material and recycle it into the ecosystem as nutrients.

They keep an ecosystem free of the bodies of dead animals, or carrion. Scavengers play an important role the food web. Carnivores and omnivores are secondary consumers. Herbivores, carnivores, and omnivores are consumers. Autotrophs are called producers, because they produce their own food. Scavengers, other carnivores, and omnivores, organisms that consume both plants and animals, are the third trophic level. Herbivores, or organisms that consume plants and other autotrophs, are the second trophic level. Autotrophs, organisms that produce their own food, are the first trophic level. Organisms in the food web are grouped into trophic, or nutritional, levels. Scavengers are a part of the food web, a description of which organisms eat which other organisms in the wild. While most carnivores hunt and kill their prey, scavengers usually consume animals that have either died of natural causes or been killed by another carnivore. Many scavengers are a type of carnivore, which is an organism that eats meat.
Original article on Live Science.A scavenger is an organism that mostly consumes decaying biomass, such as meat or rotting plant material. Knowing how bodies degrade in the ocean can give rescue divers a sense of what to look for, as well as manage the expectations of family members of those lost at sea, Anderson said.įollow Tanya Lewis on Twitter and Google+. In fact, it's quite normal for ocean scavengers to gnaw off feet, and the running shoes simply make the body parts float, Anderson said. This kind of research helps solve mysteries such as the " floating feet" found wearing running shoes that have washed up along the West Coast in recent years. "Now we have a very good idea of how bodies break down underwater," Anderson said. But when oxygen was low, the larger animals didn't come, and the smaller animals couldn't feed. So as long as the carcass entered the water when oxygen conditions were tolerable, the larger animals would feed, opening the bodies up for smaller critters and the squat lobsters, Anderson said.

But the smaller animals' mouths aren't strong enough to break the skin of the pigs.
The big scavengers (Dungeness crab and shrimp) need more oxygen to smaller creatures like the squat lobsters. When the researchers dropped the first two pigs into the water, the oxygen levels were about the same, but when scientists dropped the third body in, the levels were lower. The Saanich Inlet is a low-oxygen environment, and has no oxygen during some times of the year, Anderson said. The third body likely took so much longer due to the levels of oxygen in the water, the researchers found. Shrimp, Dungeness crabs and squat lobsters all arrived and started munching on the bodies a shark even came to feed on one of the pig corpses.Scavengers ate the first two bodies down to the bones within a month, but they took months to pick the third one clean.
It didn't take long for scavengers to find the pigs. At the end of the study, the scientists collected the bones for further examination. The researchers monitored what happened to the pig bodies using the live VENUS cameras, which they could control from anywhere with an Internet connection, and sensors that could measure oxygen levels, temperature, pressure, salinity and other factors.
