These organisms play a crucial role in benthic ecosystems, forming essential food chains and participating in the nitrogen cycle. [8] Detritivores and decomposers that reside in the desert live in burrows underground to avoid the hot surface since underground conditions provide favorable living conditions for them.
A 2016 USDA map. According to the Medley Food Desert Project, in 2017, nearly 24 million Americans lived in food deserts.
