  5. Parasitic plantsobtain some of their nutrients, especially nitrogen and minerals, by killing and digesting insects and other small animals. They grow in habitats where soils are poor in nitrogen and other minerals (acid bogs). Organic matter decays so slowly in acidic soils that there is little inorganic nitrogen available for plant roots to take up. Ex. Venus flytrap.
