Carnivorous Plants
Carnivorous plants, also called insectivorous plants are plants which typically live in very low nutrient areas and have adapted to obtain nutrients by trapping and consuming animals and insects.
There are estimated to be around 600 known species of carnivorous plants, using various mechanisms and methods for obtaining their nutrients. Some common examples of carnivorous plants include Venus Fly trap (Dionaea) Pitcher Plants (Nepenthes, Serracenia), Sundews (Drosera), Butterworts (Pinguicula) Bladderworts (Utricularia).
Generally because of their naturally low nutrient habitats carnivorous plants are best watered with rain water or distilled water as salts and minerals of which other plants will use or flush out, may build up in carnivorous plants.
