BERLIN, GERMANY - JULY 20: A Venus fly trap consumes a dead fly as it sits on display at a presentation of carnivorous plants at the Berlin-Dahlem Botanical Garden on July 20, 2013 in Berlin, Germany. Carnivorous plants derive most of their nutrients by consuming animals, most commonly flying, foraging, or crawling insects, and have adapted to grow in places where the soil does not contain enough nutrients for them to survive.
