Answer:
parasite is an organism that lives in another organism, called the host, and often harms it. It depends on its host for survival. Without a host, a parasite cannot live, grow and multiply. ... Parasites, unlike predators, are usually much smaller than their host and they reproduce at a faster rate
Carnivorous ( insectivorous) plants are plants that derive some or most of their nutrients from trapping and consuming animals or protozoans, typically insects and other arthropods.
one of the mode of nutrition is parasitic mode of nutrition in which we use two terms host and parasite .
Parasite are those organism which feed on other organism for their food and the organism parasite feed on is called host.
Insectivorous Plants- these are the plants which eat little insects as their food
