Expert Answer:

Insectivorous plants also called carnivorous plants grow in nitrogen deficient environment. They capture insects, spiders, crustaceans, mites and protozoans and obtain nitrogen. One of the most critical plant nutrients is nitrogen which is usually taken up by plants in the form of nitrates. Nitrogen is a nutrient that is easily leached out even from ordinary soils. Therefore, the plants that grow in these soils have evolved into carnivorous plants that capture and digest insects as a means of obtaining nitrates.
