Why insectivores plants are partially autotrophs and partially heterotrophs?
Nature of insectivorous plants:
The insectivorous plants depend on trapping and digesting insects which acts as the source of nutrients as it grows in nutrient-deficient soil. This acts as the heterotrophic character of the insectivorous plant.
There are green parts of the insectivorous plants except the traps where photosynthesis occurs, making them partially autotrophic as well.
Therefore, insectivorous plants get their nutrients in both an autotrophic and a heterotrophic manner.
