Imagine a plant of extremely variable height that is pollinated by three different pollinators, one that was attracted to short plants, another that preferred plants of medium height and a third that visited only the tallest plants. If the pollinator that preferred plants of medium height disappeared from an area. What is concluding of this condition?

  1. Selection pressures act against plants in the middle of the trait distribution is a result of disruptive natural selection

  2. Selection pressures act against plants in the short and medium of the trait distribution is a result of directional natural selection

  3. Selection pressures act against plants in the short and tall of the trait distribution is a result of stabilized natural selection

  4. Selection pressures random act against plants in the any of the trait distribution is a result of cyclic natural selection
