Plants have autotrophic mode of nutrition as they contain chlorophyll pigment. Thus, they have the ability to prepare their own food by the process of photosynthesis. However, some insectivorous plants are partially heterotrophic.
They have various means of capturing insects so as to supplement their diet with required nutrients derived from insects, causing proliferation of growth.
The examples include pitcher plant (Nepenthes), Venus fly trap, bladderwort, and sundew plant.
