The food chain, in ecology, is the sequence of transfers of matter and energy in the form of food from organism to organism. As the below image suggests, the desert food chain is a diagram showing the energy transfer between organisms in the desert biome. The desert food chain includes producers, organisms that make their food, consumers, or organisms that must eat to get energy. In the desert, the producers are usually grasses, cacti, and small trees. Herbivores include animals like insects and small mammals like ants and squirrels. In the desert biome, some small mammals eat both plants and animals. The grasshopper mouse eats both types of grass, like brittlebush and grasshoppers. Lastly, snakes, scorpions, and hawks are all examples of carnivores in the desert.
