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.

Answer 1

The flask's carrying capacity for rotifers is the maximum population the environment can sustain. From the data provided in the graph, we can see that the highest number of rotifers with water fleas occurs on Day 10, with 1,600 rotifers.

Therefore, the carrying capacity for rotifers in the presence of water fleas is 1,600. However, since this option is not listed among the responses, the best interpretation of carrying capacity from the choices given does not appear to be correctly represented.

Among the given choices, if we had to infer a possible carrying capacity based solely on the presence of water fleas and their impact on the rotifer population, it would be more about the population trend rather than a static number presented.

The best answer if limited to the options presented and considering interactions, would be 1,800, based on the idea that it is the next logical number above significant decline once water fleas exert their predatory effects.

So 1,800 stands as a workaround in this context given the choices.
