According to the University of California Museum of Paleontology, the grassland biome is usually a large, flat area dominated by grasses. There may be few or no trees. Fungi are present in the food web of the grassland biome in the role of decomposers.
Producers and Primary Consumers
All grassland biomes begin with grasses as the green plant producers in the food web. According to educator Sheri Amsel, the food web in an African savannah includes herbivores, such as zebras and elephants, as primary consumers of the grass.
Secondary Consumers and Scavengers
Secondary consumers are carnivores, such as cheetahs, who feed on primary consumers. Scavengers like vultures and hyenas consume food left by the secondary consumers.
Decomposers include insects, microorganisms in the soil and fungi. Their role is to break down organic waste and dead material and return it to the soil, which in turn nourishes the grasses.
