Why insectivorous plants trap insects?
(a) They can't get sufficient nutrients as nitrogen from soil.
(b) They want to take sometimes different nutrition as juices of insects.
(c) They are autotrophs and some autotrophs are not able to make food.
(d) Once on a week, they used their digestive system.
Correct Answer: (a) They can't get sufficient nutrients as nitrogen from the soil.
Explanation:
Insectivorous plants like pitcher plant and venus-fly-trap are green and carry out photosynthesis to obtain a part of the food
required by them, but they lack some of the vital nutrients such as nitrogen since they grow in nitrogen-deficient soil.
So, to recompense these nutrients they trap and eat some insects and thus they are said to be partial heterotrophs.
