Carnivorous plants do get nutrients and energy from the soil and air.
However, carnivorous plants live in boggy areas where the soil lacks many nutrients that most plants need to survive.
Bug supplements make it possible for these plants to live in their natural habitat.
Charles Darwin first wrote about carnivorous plants in 1875. There are over 300 proto-carnivorous plant species that show some but not all these characteristics.
There are five basic trapping mechanisms are found in carnivorous plants, and the traps may be active or passive, depending on whether movement of the plant helps the capture of prey.
1. Pitfall traps, or pitcher plants, trap prey in a rolled leaf that contains a pool of digestive enzymes or bacteria that slowly digest the victim.
2. Flypaper traps use a sticky mucilage like that on a frog’s tongue.
3. Snap traps utilize rapid leaf movements to surprise and trap their prey.
4. Bladder traps suck in prey with a bladder that generates an internal vacuum.
5. Lobster-pot traps force prey to move towards a digestive organ with inward-pointing hairs.
