Correct option is A
The correct answer is Nutrients.
Carnivorous plants obtain the essential nutrients from the heterotrophs. These plants trap insects and obtain the nutrients which they do not get from the soil. They are not called heterotrophs or consumers, because they only derive nutrients from insects. These plants get energy from the process of photosynthesis. Hence they are bot producers and carnivorous.
Plant Trapping technique
Pitcher plant Leaves transformed
into a slippery deep
pool containing
digestive juices.
Insects fall into
these pools and
plant digests them.
Venus Flytrap It has snap traps,
which snap shut
when touched by
insects.
Sundew It has a sticky
substance on its
surface which looks
like dews.
The insect gets
stuck on it and
digestive juices
digest it by the time.
Thus, these plants derive nutrients from insects.
