Different between insectivorous and symbiotic plants?
Insectivorous means those that consume insects.
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 include the Venus flytrap, several types of pitcher plants, butterworts, sundews, bladderworts, the waterwheel plant, brocchinia and many members of the Bromeliaceae.
Symbiosis is a mutual relationship between 2 organisms or more. They coexist as a single being, mutually benefitting each other or by benefitting one and harming the other.
Symbiosis is any type of a close and long-term biological interaction between two different biological organisms, be it mutualistic, commensalistic, or parasitic. The organisms are each termed a symbiont.
Mutualism is seen in lichens.
Parasites are tapeworms and pigs, etc.
Commensalism is seen in mites and flies, etc.
In mutualism, both organisms are benefitted. In Commensalism, one is bemefitted, other has no effect. Parasitism, one benefits , other suffers.
