Quoted: “In environments that are sunny and moist but nutrient-poor, the capture of prey can give plants a real competitive advantage,” said Thomas Givnish, a professor of botany at the University of Wisconsin-Madison. Carnivorous plants thrive in open bogs; in damp, fireswept sand; by roadside puddles; in the leached mud of a mountainside — bright, sodden spots where competitors are negligible, the insects gullible, and nutrients alone limit plant growth.
