Desert (Arid Biome)

Arid biome receiving under 250 mm of annual rainfall, where succulence, CAM photosynthesis, and ephemeral seed banks enable plant survival.

Core Principles & Analysis

• Conventionally defined by less than 250 mm of annual precipitation.
• Cacti and other succulents use CAM photosynthesis, opening stomata only at night to conserve water.
• After rare heavy rains, dormant seed banks erupt in mass 'superbloom' flowering events.
