Round-leaved sundew (Drosera rotundifolia) is a species of carnivorous plant that grows in bogs, marshes and fens. The plant uses enzymes to dissolve the insects – which become stuck to the glandular tentacles – and then extracts ammonia (from proteins) and other nutrients from their bodies. The ammonia replaces the nitrogen that other plants absorb from the soil, and plants that are placed in a high-nitrogen environment rely less upon nitrogen from captured insects. One of the most widespread sundew species, it has a circumboreal distribution, being found in all of northern Europe, much of Siberia, large parts of northern North America, Korea and Japan.
