Use the graph to answer the question below.

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.

To determine the flask's carrying capacity for rotifers in the presence of water fleas, we need to identify the maximum number of rotifers that can be sustained when both rotifers and water fleas are present.

From the data provided:

  • The maximum number of rotifers recorded with water fleas is at Day 10, which is 1,700.
  • At Day 12, the number of rotifers with water fleas decreases to 1,500, and it continues to decline.

Thus, the carrying capacity of rotifers in the presence of water fleas is represented by the highest number found in the data when both are present. Therefore, the flask’s carrying capacity for rotifers with water fleas is 1,700.

However, since this option isn't explicitly provided in the responses, it appears the options might reflect estimated or typical values based on the trends observed in the data rather than exact figures.

Given the choices provided:

  • 3,000
  • 1,800
  • 4,200
  • 0

The closest value to the observed maximum of 1,700 is 1,800.

So, the most reasonable choice to select based on the information is 1,800.
