What Information Is on a Desert Food Chain Diagram?


Information on a desert food chain diagram includes the primary producers, the primary consumers, small predators and the larger predators for the desert biome. Small predators are comprised of both carnivores and insectivores, sometimes known as the secondary consumers. Larger predators are sometimes called the tertiary consumers.

The primary producers on a desert food chain diagram are cacti, creosote bushes, thorn acacias, annual flowers and rabbit brush. Ocotillo and sage brush also fit into this category. Primary producers make their own food, and so are at the bottom of the food chain. Primary consumers are the herbivores that eat the primary producers. In a desert biome, these include insects, lizards, rodents and kangaroo rats.

Next in the desert food chain are small predators, such as tarantulas, scorpions, tortoises, snakes and quail. Larger predators on the desert food chain are hawks, owls, foxes and vultures. These are meat-eaters, and they consume the smaller animals. Each level on the food chain contains fewer animals, because the larger the animal, the more it must eat.

Some desert food chains include the decomposers and detrivores. These eat the dead plants and animals in the desert. Included in this category are mushrooms, fungi, some insects and bacteria.
