Africa is the world’s second largest continent with 20 percent of the Earth's land mass. The African continent is home to a variety of ecosystems, from hot deserts, to tropical rain forests. Approximately half of Africa is covered by savannas of some sort (about five million square miles), beginning just below the tropic of Cancer and continuing down to the tropic of Capricorn. The circulation of the atmosphere over Africa is dominated by areas of high pressure centered over adjacent oceans around the Tropics of Cancer and Capricorn. These areas produce winds from East to Northeast, over the Sahara and the Kalahari. These regions are arid because they are occupied by dry, subsiding air for most of the year. Moist air moving into Africa, mainly from the South Atlantic and the Indian Ocean, is monsoonal in character. The humid, unstable air moves inland in summer. The seasonality of the rainfall is an extremely important determining feature in the climate almost everywhere in Africa. Grasslands can be broken up into two main categories, the first being tropical grasslands, called savannas, and the second being temperate grasslands. Savannas are characterized by grassland with scattered individual trees. Savan
Southern Africa is a highly sensitive region due to its increasing population and population migration, rain-fed
subsistence agriculture, limited water and food availability, and relatively low industrial development. However, recent political and social stability has led to more rapid though economic and industrial development. Energy
Lions are really secondary carnivores, preying on both herbivores and smaller carnivores. They are very social animals, living in groups or families called prides. They spend up to 20 hours a day resting. During their resting period they gather in their prides and play together and rub their heads together. Lions hunt cooperatively, often stalking their prey and attacking in groups, as they do not have the endurance to run. A pride generally has only two males and several females and their offspring. Females will stay together for life, but the position of a male in a pride is not permanent. Males must fight for possession of the pride and do not remain in the pride if they are not strong enough to defend it (Alden, et. al., 1995).
