Which biome features dry conditions with limited vegetation?

Deserts are characterized by their arid conditions and significant limitations on vegetation due to the low amounts of rainfall they receive, typically less than 250 mm (10 inches) annually. This environment leads to unique adaptations among the plants and animals that inhabit these regions. The sparse vegetation primarily consists of drought-resistant plants such as cacti, succulents, and deep-rooted shrubs, which have evolved to conserve water.

In contrast, forests, savannas, and grasslands generally have more moisture, which supports a greater diversity and density of plant life. Forests thrive in more humid conditions, savannas feature a mix of grasslands and scattered trees typically in regions with seasonal rainfall, and grasslands are characterized by more extensive and denser vegetation than deserts. Thus, the key distinguishing factor of the desert biome is its dry climate and limited vegetation, making it the correct answer.
