Imagine you are an ecologist who has been studying the ecosystems of ponds. You notice that the size of Koi varies depending on the size of the pond. You

if the size of the fish was proportional to the size of its habitat (ie, the bigger the pond, the bigger the
fish)
what problem is this experiment trying to solve? (Does theaffect the ?)
