Class 11 Biology - Chapter Biological Classification NCERT Solutions | Plants are autotrophic. Can you think of
Plants are autotrophic. Can you think of some plants that are partially heterotrophic?
Plants have autotrophic mode of nutrition as they have the ability to synthesize their own organic food by process of photosynthesis due to presence of green pigments chlerophylum. However, some insectivorous plants are partially heterotrophic. They have various means of capturing insects so as to supplement their diet with Nitrogen derived from insects, as they live in nitrogen deficient soil. The examples include pitcher plant (Nepenthes), Venus fly trap, Bladderwort and sundew plant (Drosera).

Good question thanks for the saralstudy
The best answers I could find. Thanks a lot
Autotrophic organisms can be studied in where?
Can you pleace explain shortly
Good to understand
Gabar sawal ka Thakur jabab.

super helpful
Nice to whoever have done thisð
