Up to 12mph
Opens its mouth when it feels theatened

Oxpecker gets fed
Rhino gets rid of pests and warned of danger Parasitism Ticks and Elephants The ixodid tick takes blood from the elephant
The tick's fitness increases
The elehant's fitness decreases http://www.discoverlife.org/20/q?search=Arthropoda Competition Lions and Hyenas Lions and hyenas prey on many of the same animals, which leads to competition between the two species. http://gilesbowkett.blogspot.com/2008_04_01_archive.html Commensalism Lions and Vultures http://ourdems.org/kenya/p6MasaiMara2.htm A lion kills an animal, the vulture gets the "leftovers"
The vulture gains
The lion is unaffected Biotic Factors Vegetation
(jackalberry trees, umbrella thorn, bermuda and elephant grasses)
(rhinos, snakes,lions, cheetahs, elephants, etc.)
Abiotic Factors Fires from seasonal lightning
Soil Human Influence Desertification Areas of desert are created by the destruction of natural vegetation
Results from: removal of vegetation cover, overgrazing, uncontrolled wood collection Extinction Humans excessively hunting select animals lowers their numbers
Lions and African Wild Dogs
African Elephants hunted for their tusks http://www.bbc.co.uk/schools/gcsebitesize/geography/ecosystems/human_savrev1.shtml http://ecocheetah.wikispaces.com/Examples http://biomea.wikispaces.com/Grassland http://www.blueplanetbiomes.org/savanna.htm http://usclimatedata.com/images/climate-chart/usga0507-climate-savannah-hunter-aaf.gif http:/fundivision.net/?p=2709; Katie Jessica The Savanna Less rain than tropical dry forests, more rain than deserts
Strong winds and frequent fires discourage tree growth
Plants grown quickly and recover from fire damage quickly
