based on the information in the graph which statement best expalins whether the duckweed population in group 3 reached its carrying capacity during the 6 weeks of the experiment

The possible answers are:

Answer 1 : After about 3 weeks, the population reached its carrying capacity of about 250 plants.

Answer 2 After about 4 weeks, the population reached its carrying capacity of about 225 plants.

Answer 3 The population did not reach its carrying capacity because it was still slowly increasing.

Answer 4 The population did not reach its carrying capacity because it was declining at the end of the experiment.

The correct answer is Answer 1

As we can see from the graph presented below, population 3 in this experiment with duckweed has been growing in an environment rich in nutrients and light. After 3 weeks of the experiment this population has reached a number of 250 individuals and stopped growing. This is a good indicator that this population has reached the limit of the carrying capacity of the environment.
