  rdf:value "Crassulacean acid metabolism (CAM) is a photosynthetic adaptation to periodic water supply, occurring in plants in arid regions (e.g., cacti) or in tropical epiphytes (e.g., orchids and bromeliads). CAM plants close their stomata during the day and take up CO2 at night, when the air temperature is lower and water loss can be lowered by an order of magnitude."@en ;
