Examine the graph to answer the question below.

Question

The graph shows number of rotifers on the y-axis from 0 to 4500, in increments of 500. The x-axis is labeled as days. The data is as follows. Day 0: number of rotifers alone and number of rotifers with water fleas, 0. Day 2: number of rotifers alone and number of rotifers with water fleas, 0. Day 4: number of rotifers alone and number of rotifers with water fleas, 300. Day 6: number of rotifers alone and number of rotifers with water fleas, 500. Day 8: number of rotifers alone and number of rotifers with water fleas, 800. Day 10: number of rotifers alone, 1700 and number of rotifers with water fleas, 1600. Day 12: number of rotifers alone, 3000 and number of rotifers with water fleas, 1500. Day 14: number of rotifers alone, 4000 and number of rotifers with water fleas, 1100. Day 16: number of rotifers alone, 4200 and number of rotifers with water fleas, 200. Day 18: number of rotifers alone, 4200 and number of rotifers with water fleas, 0.

Which action may increase the flask’s carrying capacity for rotifers?

decrease the number of microorganisms

increase the number of microorganisms

introduce water fleas

decrease the size of flask

Answer 1

Introducing water fleas may increase the flask's carrying capacity for rotifers, as seen in the data where the number of rotifers with water fleas was higher than when the rotifers were alone. By introducing water fleas, there may be a symbiotic relationship or a more optimal environment for the rotifers to thrive, increasing the overall carrying capacity of the flask.
