Document Summary

Take away their neighbours (reduce competition) open pitchers is a huge advantage: in the experiments on pitcher plants, the results suggested little competition for soil nutrients between them and non-carnivorous neighbors, competition for light was more important. Grows mostly when other competitors are reduced from fire allows to escape competition for nutrients by reducing demand for scarce nutrients when competition is more intense i. e. in years without fires. Basically it increases nutrient demand when there"s a fire because other plants aren"t as good. Over half the species on earth get energy by feeding on other organisms, in a variety of types of interactions: all are exploitation: a relationship in which one organism benefits by feeding on, and directly harming, another. Herbivore: eats tissues of living plants or algae. Predator: kills and eats other organisms, referred to as prey. Parasite: lives in or on another organism (its host), feeding on parts of it.
