Document Summary
Case study: competition in plants that eat animals: Many plants eat animals through variety of mechanisms like physically eating it or luring them in with nectar. Plants are carnivorous because of competition with neighbors for soil nutrients. Carnivory in plants is an adaptation for life in nutrients -poor environments. Perhaps providing a way to avoid competing with other plants for soil nutrients. Tansley concluded that the 2 species competed with each other, and that when grown on its native soil type, each specie drove the other to extinction. G jercynicum (acidic soil) vs g pumilum (calcareous soil) Organisms compete for resources, which are features of the environment that are required for growth , survival, or reproduction and which can be consumed or otherwise used to the point of depletion. Competition occurs between organisms that share the use of a resource that limits their growth, survival, or reproduction.
