Examine the graph the answer the question below.

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 carrying capacity of a population is the maximum number of individuals that an environment can sustainably support. Based on the data provided for the number of rotifers alone on different days, we can identify the peak population reached in the absence of water fleas.

From the provided data for the number of rotifers alone:

• Day 10: 1700
• Day 12: 3000
• Day 14: 4000
• Day 16: 4200
• Day 18: 4200

The maximum number of rotifers alone is observed to be 4200 on Day 16 and maintained at that level on Day 18. This indicates that the carrying capacity of the flask for rotifers in the absence of water fleas is 4200.

Therefore, the flask’s carrying capacity for rotifers in the absence of water fleas is 4,200.
