Document Summary
Competition in plants that eat animals: a case study. Plants use a variety of mechanisms to eat animals. Venus flytrap - modified leaves that look like teeth/jaws. Once the insect is captured the trap tightens further - forming air tight seal. Other plants lack moving parts - yet can still eat plants. Pitcher plants - can use nectar or visual cues to lure insects. Plants are rooted in the ground and cannot move in search of food. Competition among plants can be intense where soil nutrients are scarce. Many carnivorous plants are found only in environments with nutrient poor soils. Root systems of carnivorous plants are less extensive than those of noncarnivourous plants that live in the same area. Suggests that the carnivorous plants may be poorer competitors for soil resources. Competition decreases growth in a carnivorous plant. A. g tansley did one of the first experiments on competition in 97.
