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.

The carrying capacity for rotifers in the presence of water fleas can be determined by looking at the number of rotifers at the point when their population levels off, despite the presence of water fleas. Based on the data you provided, it appears that the number of rotifers with water fleas peaked at 1,700 on Day 10 and then began to decline after that, suggesting that the carrying capacity is around that value.
Hence, the correct response is:
1,800.
