The desert “supports a vibrant ecosystem teeming with life.” “Teeming” means full of, so the desert is full of life, but only people who look deeply see that. The blank, then, must be filled by words that mean the opposite of full of life. “Desolate,” which means bleakly empty, and “inhospitable,” which when describing an environment means hard to live in, both fit: casual observers don’t see much life in deserts. Although “arid” and “dessicated” both mean dried up and seem like good descriptions of a desert, they are not correct because they are not opposites of “teeming.” “Verdant” and “lush” are a reversal trap, as both are used to describe an environment that is full of greenery and plant life.
