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.

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

Answer 1

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

Looking at the data provided:

• At Day 12, the number of rotifers with water fleas is 1500.
• At Day 14, the number is 1100.
• At Day 16, it drops to 200.
• At Day 18, it reaches 0.

The highest count of rotifers with water fleas occurs at Day 12, which is 1500.

Thus, the flask’s carrying capacity for rotifers in the presence of water fleas is 1,800.
