Question

how does the pitcher plant catch its food​

Answer 1

Answer:

Pitcher plants (or pitfall traps) are carnivorous plants whose prey-trapping mechanism features a deep cavity, formed by a cupped leaf and filled with a digesting liquid. Insects such as flies are attracted to the cavity, often by visual lures such as anthocyanin pigments, and nectar bribes,

The sides of the pitcher are slippery and may be grooved in such a way so as to ensure that the insects cannot climb out. Then, through a mechanism of digestion, the prey is converted into a solution of organic and inorganic chemicals, such as amino acids, peptides, phosphates, ammonium and urea. The plant obtains its mineral nutrition (particularly nitrogen and phosphorus) and can survive in locations where the soil is too poor in minerals and/or too acidic for most plants to be able to grow.

Answer 2

Foraging, flying or crawling insects such as flies are attracted to the cavity formed by the cupped leaf, often by visual lures such as anthocyanin pigments, and nectar bribes. The rim of the pitcher (peristome) is slippery, when moistened by condensation or nectar, causing insects to fall into the trap.
