Explanation:

In 5 years time the turtle population reached the carrying capacity of the  pond. Carrying capacity of pond refers to the population of marine animals such as fishes, turtles etc can live and survive on the natural food available in the pond. If the food is present in large amount, than carrying capacity of the ecosystem is large. In pond ecosystem, the population of turtle decreases because the food is not sufficient to feed the existing population.
