Figure 2: A partial depiction of a Savanna biome food web. Arrows designate the direction of food energy flow between trophic levels. The picture does not depict the level below the primary producers. This is an extremely important level of detritivores and decomposers, microscopic animals and insects whose life processes cycle key elements like carbon, nitrogen, and phosphorous back into the soil.1
