Some species of plants are insectivorous. Why?
- ATheir growth in shady and dark places does not allow them to undertake sufficient photosynthesis and thus they depend on insects for nutrition
- BThey are adapted to grow in nitrogen deficient soils and thus depend on insects for sufficient nitrogenous nutritionCorrect
- CThey cannot synthesize certain vitamins themselves and depend on the insects digested by them
- DThey have remained in that particular stage of evolution as living fossils, a link between autotrophs and heterotrophs
Explanation
The correct answer is B because insectivorous plants typically grow in marshy, acidic, or sandy soils where nitrogen is severely lacking. While these plants can perform photosynthesis to produce sugar, they cannot obtain enough nitrogen from the soil to build essential proteins and DNA. To overcome this deficiency, they have evolved specialized traps to capture and digest insects, using the nitrogen from the insects bodies as a vital nutrient supplement for their growth.
