The statement that most accurately reflects the significance of factors affecting the carrying capacity based on the scale of the ecosystem is:
Overfishing has a more significant impact on the carrying capacity of the ocean bay than the pond.
This is because the larger size and complexity of the ocean bay ecosystem allows for a greater scale of fishing activities, which can lead to more pronounced effects on fish populations. In contrast, the smaller pond may have more localized and easily observable impacts due to its limited size and resources.
