Question

Insectivorous plants that mostly grow on swampy soil use insects as a source of–
(A) Carbon
(B) Nitrogen
(C) Phosphorous
(D) Magnesium

Answer 1

Hint: Insectivorous plants are the plant types that extract nutrients from insects and other species. However, through photosynthesis, these plants derive their energy. They grow in soil without any nutrients, which they get by feeding animals.

Complete answer:The plants that receive some or most nutrients by capturing and eating insects are insectivorous plants or carnivorous plants. Carnivorous plants are plants derived from capturing and eating mammals, usually insects, and other arthropods, some or most of their nutrients. Carnivorous plants have adapted for the growth of soil in areas where the nutrients, especially nitrogen, are thin or low, such as acid bowls. Photosynthesis is their source of energy. These plants are suitable for growing in areas with low to poor soil in nutrients. Nitrogen is the most common shortfall. It grows in wetlands where sunlight and moisture such as swamps, wetlands, slopes and coastal lands, etc are appropriate. The insects are trapped and digested for nitrogen. Many plants have modified or special plant parts to trap insects. Some plants release digestive enzymes or chemicals to absorb insects. The plants appear vibrant and colorful, releasing nectars or fun smells that attract insects. Exhibits of insectivorous plants include Drosera, Venus flytrap, Nepenthes, Genlisea, etc.

Thus, an option(A) - Nitrogen is the correct answer.

Note: The plants that thrive in areas where the soil is low in nutrients are insectivorous (mainly nitrogen). They also changed plant parts to acquire their nutrients by trapping the insects and digesting them with chemical substances or enzymes to generate nitrogen and other nutrients.
