plants produced large tough seeds and small soft seeds. Most members of a population of finches are found to have small beaks while a smaller portion of the group have large beaks. The islands experienced a drought that negatively impacted the community of plants that produced small soft seeds leaving the island with plants that produced large tough seeds. After the drought, it was observed that the finches with smaller beaks were reduced and the majority of finches were found to have large beaks.

7) The term "preemptive competition" refers to _________________. Question 7 options: when individuals of one species inhibit individuals of another by consuming a shared resource situations where the occupancy by one individual precludes the establishment of others when one organism grows over another, thereby inhibiting access to some essential resource when chemical growth inhibitors inhibit germination and establishment of other species when nonterritorial meetings between individuals negatively affect one or both of the participant species
