carnivorous plants feed mainly on insects.this is simply an adaptation process which is helps them cope with existence.their habitats differs from many others as soil is not too favourable,hence the adaptation process in meant for them to obtain nutrients from the insects they consume,thus they are also referred to as insectivorous.
Carnivorous plants adapt to the environment in many ways. They evolve in acidic and nutrient poor soils and do not adapt well to soil borne nutrients. Most carnivorous plants are found in bogs. Because they are found there, it is difficult for them to dry. When there is a lack of soil consisting of a few nutrients, the plants are able to trap insects, digest them as well as absorb them. The Venus Fly Trap is also an example of a carnivorous plant. They are typically found in their native land which is found in South Carolina’s northeast coast and North Carolina’s coastal planes. They capture prey through modified leaves where they develop traps at the end of the lead.
The most common habitat for carnivorous plants is in bogs and fens. One of the advantages to living in a bog or fen is that water and sunshine are abundant all year long; however, there are disadvantages to these particular habitats, as well. One the downsides of bogs and fens is that they tend to be have low nutrient densities. One such nutrient that is lacking in the soil of bogs and fens is nitrogen. Normally, a plant can get all of the nitrogen that it needs from the soil, but carnivorous plants live in areas where that isn't possible. They have to obtain that nutrient from other sources, so they have adapted themselves to capture various invertebrates. While insects are the most common nutrient source for carnivorous plants, sometimes mammals and frogs can be used as well.
