Arkive describes the African savannah as a vast grassland ecosystem with consistently warm temperatures, making it an ideal habitat for a wide variety of animals. African food chains vary slightly depending on location, but Arkive explains that each one consists of herbivores, carnivores, scavengers, decomposers and producers.
ExploringNature.org explains that the vulture and hyena are prime examples of scavengers, and producers on the African savannah include trees, grass and shrubs. Mushrooms, tiny organisms and insects such as dung beetles are Africa's decomposers.
According to Wikipedia, apex predators are at the top of any food chain. An apex predator is a predator that does not fall prey to others once it reaches adulthood. Scavengers such as vultures are not considered apex predators because they don't depend on catching live prey. Wikipedia states that the major apex predators in the African savannah include the black-backed jackal, African wild dog, African lion, cheetah, chimpanzee, honey badger, mandrill, leopard and Nile crocodile. Predators are called secondary consumers in food chains.
TheSafariGuide.net lists herbivorous animals in the African food chain, including the zebra, many different antelope species, wildebeest, giraffe and warthog. Wikipedia states the elephant, rhinoceros and hippopotamus are the three largest African herbivores and have nothing to fear from predators other than humans. Herbivores are called primary consumers in food chains.Learn More
Most extinctions can be prevented by implementing conservation strategies such as legal remedies, preserving natural plant and wildlife habitats and using synthetic medicines not derived from plant and animal products. Preventing extinction requires an understanding of its root causes, which include natural events and human activity. Although extinctions from natural causes cannot be prevented, human behavior may be modified to give flora and fauna worldwide a greater chance of survival.Full Answer >

Remora and sharks have a commensalism relationship which, according to the Encyclopedia Britannica, is a relationship between two species in which one benefits from the other without either being harmed. Commonly called a suckerfish, the remora is a pelagic marine fish that attaches to the shark and feeds on it. Unlike parasitic species, the remora does not penetrate the flesh of the shark or otherwise cause it damage.Full Answer >
