Microbes live off of the energy released from these chemical reactions and form the basis of ecosystems for as long as the food source lasts.Īt deep sea levels this forms a new food web and provides energy to support single- and multi-cell organisms and sponges, thus adding to the ocean's food chain. The whale skeleton can support rich communities for years to decades, both as a hard substrate (or surface) for invertebrate colonization and as a source of sulfides from the decay of organic compounds of whale bones. Organic fragments, or detritus, enrich the sediments nearby for over a year. food chain, in ecology, the sequence of transfers of matter and energy in the form of food from organism to organism. Scavengers consume the soft tissue in a matter of months. When whales die and sink, the whale carcasses, or whale falls, provide a sudden, concentrated food source and a bonanza for organisms in the deep sea.ĭifferent stages in the decomposition of a whale carcass support a succession of marine biological communities. But scavengers are not the only organisms that want to feed on. Many scavengers are a type of carnivore, which is an organism that eats meat. The ocean's depths are supplied by nutrients falling down from the surface waters. When an animal dies, the nutrients stored in its body suddenly become available for scavengers. What are Scavengers in a Food Web Vultures, Coyote, Striped Hyena, Jackals, Bottle flies, Piranha, Crabs, Ravens, Lions, Foxes, etc. A scavenger is an organism that mostly consumes decaying biomass, such as meat or rotting plant material. During a 2019 expedition, researchers discovered a whale fall at 10,623 feet below the surface near Davidson Seamount in NOAA's Monterey Bay National Marine Sanctuary.
