''
Insectivorous plants are plants that derive some of their
nutrients from trapping and consuming animals or
protozoan. The benefit they derive from their catch varies considerably; in some species, it might include a small part of their nutrient intake and in others it might be an indispensable source of nutrients. As a rule, however, such animal food, however valuable it might be as a source of certain critically important minerals, is not the plants' major source of
energy, which they generally derive mainly from photosynthesis. Insectivorous plants might consume insects and other animal material trapped adventitiously. However, most species to which such food represents an important part of their intake are specifically, often spectacularly, adapted to attract and secure adequate supplies. Their prey animals typically, but not exclusively, comprise
insects and other
arthropods. Plants highly adapted to reliance on animal food use a variety of mechanisms to secure their prey, such as pitfalls, sticky surfaces, hair-trigger snaps, bladder-traps, entangling furriness, and lobster-pot trap mechanisms. ==See also==
