Final answer:
The relationship among time, food, and the P. aurelia population indicates that as time passes, the P. aurelia population decreases due to limited availability of food in the container. P. aurelia outcompetes P. caudatum for the same resources, suggesting a higher efficiency in utilizing available food. The graph and information show that the P. aurelia population is influenced by the availability of food and its growth is inversely proportional to time as the food supply depletes.
Step-by-step explanation:
The relationship among time, food, and the P. aurelia population can be described based on the information and graph. As shown in the graph, the number of cells of P. aurelia decreases over time. This indicates that as time passes, the P. aurelia population decreases. The decrease in population may be due to the limited availability of food in the container. As the P. aurelia cells consume the available food, the population declines.
The relationship between food and the P. aurelia population can be explained by the concept of resource competition. When P. aurelia and P. caudatum are grown together in the same container, P. aurelia outcompetes P. caudatum for the same resources. This suggests that P. aurelia has a higher efficiency in utilizing the available food compared to P. caudatum. As a result, P. aurelia is able to thrive and grow well when food is abundant.
Overall, the graph and information indicate that the P. aurelia population is influenced by the availability of food, and its growth is inversely proportional to time as the food supply depletes.
