Step 1:: Understand the relationship between the number of generations and the guppy population.
In this scenario, the guppy population increases with each generation without any resource limitations. This suggests an exponential growth model, where the population at any generation is a function of the initial population and the growth rate (number of offspring per adult).
Step 2:: Identify the key factors affecting guppy population growth.
The two main factors affecting guppy population growth are:
Step 3:
Initial adult population
Step 4:
Growth rate (number of offspring per adult)
Step 5:: Analyze the options based on the key factors.
Option A: Increase the number of adult guppies introduced into the pool. - This action directly increases the initial adult population, which in turn increases the number of offspring and thus the overall population growth. Option B: Improve the water quality in the pool. - While better water quality may have a positive impact on the survival rate of guppies, it does not directly increase the number of offspring per adult. Therefore, this option may not significantly affect the exponential growth rate. Option C: Provide more food for the guppies. - Similar to Option B, more food may increase the survival rate of guppies, but it does not directly impact the number of offspring per adult. Thus, this option may not significantly affect the exponential growth rate.
Step 6:: Recommend the best course of action.
Based on the analysis, Option A is the best choice for the guppy farmer. By increasing the number of adult guppies introduced into the pool, the farmer directly influences the exponential growth rate, leading to faster population growth.
Final Answer
The guppy farmer should increase the number of adult guppies introduced into the pool to produce guppies faster.
