Question

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.

Examine the graph. What is the flask’s carrying capacity for rotifers in the presence of water fleas?

Answer 1

Based on the data you've provided, the number of rotifers with water fleas appears to peak at 1700 on Day 10 and subsequently declines to 0 by Day 18. The highest number recorded with water fleas is 1700, which indicates that the flask’s carrying capacity for rotifers in the presence of water fleas is 1700.

Therefore, the answer you are looking for is **not** among the options provided (4,200, 3,000, 0, or 1,800), as the correct carrying capacity for rotifers with the presence of water fleas should be **1,700**.

However, if you must select the closest option, **1,800** could be the logical choice even though it is slightly higher than the observed peak.

The answer is **1,800**.
