Final answer:
The highest levels of competition among the plants would be found in the control plots, while the lowest levels would be found with both rodents and ants removed. Hence the correct answer is option 1
Step-by-step explanation:
In this study, it is expected that the highest levels of competition among the plants would be found in the control plots, while the lowest levels would be found with both rodents and ants removed. This is because rodents and ants are potential competitors that consume resources that the plants need, leading to higher levels of competition. When both rodents and ants are removed, the competition among the plants is reduced, resulting in lower levels of competition.
Hence the correct answer is option 1
