Food Web Diagram
The African Grasslands are areas where the vegetation is dominated by grasses and other herbaceous (non-woody) plants. Grasslands cover nearly 50 percent of the land surface of the continent of Africa. While grasslands in general support diverse wildlife, given the lack of hiding places for predators, the African Savannah regions support a much greater diversity in wildlife than do temperate grasslands. The root systems of perennial grasses and forbs form complex mats that hold the soil in place. Mites, insect larvae and earthworms inhabit deep soil, which can reach 20 feet underground in undisturbed grasslands on the richest soils of the world. These invertebrates, along with symbiotic fungi, extend the root systems, break apart hard soil, enrich it with urea and other natural fertilizers, trap minerals and water and promote growth. Some types of fungi make the plants more resistant to insect and microbial attacks.
Energy enters an ecosystem in the form of heat from the sun. This energy is absorbed by organisms such as plants, and is then converted to other forms of energy and stored. Once stored, energy is used for necessary life functions, such as growth, movement and reproduction. There are several kinds of organisms, such as bacteria, fungi, termites, grasses, trees, herbivores/omnivores, carnivores and scavengers, which can be found in the African Grasslands. The decomposers are living things (often fungi, insects or bacteria) that break down dead animals or plants and animal wastes to obtain energy and nutrients. The producers are plants (usually green) that take carbon dioxide and water and convert them to living matter using the energy of the sun. The consumers obtain its food by eating plants or by eating animals that have eaten plants.
There are four types of consumers within the African Grassland ecosystem. The herbivores (giraffes, zebras and impalas) are animals that feed mainly on plant...
