1. Since more offspring are produced than an environment can support, organisms within a population must compete for resources to survive. 2. Due to variations within the population, some competitors will be better equipped for survival than others. 3. The best-equipped organisms will survive and will produce well-equipped offspring. 4. Variations that help with survival will be passed on to future generations and will rapidly change the whole population. Which point is flawed as written above? point 1 point 2 point 3 point 4
