The insects are allured by secretion of sweet sticky substance inside the pitcher and once the insect enters to feed inside the lid of the pitcher is closed and the insect is trapped and digested.
Pitcher plants like the Venus Flytrap originate in areas where there is a deficiency of Nitrogen in the soil. In order to survive they have to supplement their requirement of Nitrogen by another means; which is the trapping and digesting of insects. Enzymes produced in the walls of the Pitcher plant help to digest any insect that may fall into the "pitcher" and become trapped. The nutrients contained in the insects are then absorbed through the walls of the pitcher to supplement its nutrient requirements.
Insect eating plants normally have modified leaves in order to trap insects - such as the "trap" in the Venus Flytrap, the "pitcher" of a Pitcher Plant and the sticky hair covered leaves of a Sundew. What they all have in common though is the ability to produce digestive enzymes in order to break down the insect body and facilitate digestion of contents the insect; the exoskeleton is not digested.
the rim of the pitcher is very slippery so the insect can't get out
In the insect gizzard, food is ground into finer particles that are more readily digested and absorbed.
Decomposition attracts insects to the decomposing object and the insects use the decomposition of that thing to provide food and temporary shelter to the new born insects or larva of that insect.
it normally eats insects,and when its not eating it waits for its prey(insect)
The pride o barbados is insect pollinated because it produces sweet nectar and is brightly coloured which attracts insects.
It is known that the floral part that attracts insect pollinators is called the petal.
Venus fly-traps and pitcher plants who has digestive enzymes to engulf insect's nutrition.
pitcher plants are grows in soil which does not have much nitrogen in soluble form. they trap insect because they have nitrogen in their bodies.
an insect touches a leaf of a sundew plant then the leaf slowly moves and covers the insect with all those sticky stuff and then digest it and the nutrients go in the plant by tiny holes leading to the roots.
