An artificial pond at a college campus was populated with several pairs of pond slider turtles. after many years of slow population growth, campus administrators installed a coin-operated food dispenser at the pond's edge. students and community members bought and fed the turtles an enormous amount of food each day. within 5 years the population of turtles in the pond was increasing exponentially. how did the installation of the food dispenser affect the carrying capacity of the turtle populations at this pond?
