Examples of scavengers include hyenas, jackals, opossums, vultures, crows, crabs, lobsters and cockroaches. Many mammals, birds, sea life and insects consume decaying organic matter when necessary but not exclusively. Lions, leopards and wolves mainly hunt for fresh meat, but eat carrion if they encounter it. Foxes and coyotes are more likely to eat carrion in the winter when food is scarce.Know More
In addition to hunting fresh kills, great white sharks eat dead whales, fish and sea lions. Black bears eat carrion when they find it, although they are regularly herbivores, consuming fruit, nuts and berries. Scavenger dogs and crows frequently feed on road kill. Burying beetles, blowflies and yellow jackets are scavengers, consuming decaying animal matter. Dung beetles eat feces.
In suburban settings, opossums and raccoons raid garbage cans for discarded food. Seagulls also feed on garbage. Some insects, such as termites, scavenge dead plant material.
Unlike animals like elephants, which are strict herbivores, scavengers are very adaptable to different and changing environments. They can adjust to whatever food is available and do well in farmland, suburban or urban settings. They play an important role in the ecosystem by keeping the environment cleaner and free of carrion. Scavengers break down decaying organic material and recycle the nutrients back into the ecosystem.Learn more about Biology
Examples of saprophytic bacteria include cheese mold, lactic acid, yeast and rotting kitchen waste. Saprophytic bacteria are fungal organisms that feed off of decaying organic matter. The term "saprophyte" refers specifically to fungal and bacterial saprotrophs, but animal saprotrophs are known as saprozoites.Full Answer >
Examples of facultative anaerobic bacteria include salmonella and E. coli. Facultative anaerobic bacteria are members of the taxonomic families Enterobacteriaceae, Vibrionaceae and Pasteurellaceae. Many of the species in these families are pathogens in humans, other animals or plants.Full Answer >
Examples of anaerobic respiration include nitrate reduction, denitrification, sulfate reduction and carbonate reduction. All of these methods use an electron acceptor other than oxygen and have a membrane-bound electron transport system. These anaerobic mechanisms also synthesize adenosine triphosphate, or ATP, through ATP synthase.Full Answer >
Examples of internal stimuli include: hunger, hormone levels, sensations of anxiety and changes in vital signs such as blood pressure. A stimulus is defined as anything that can cause a behavioral or physical change. Stimuli are both internal and external.Full Answer >
