A. higher growth in tree A; the number of aphids will fall because ants are absent, and aphids are parasites of the tree B. higher growth in tree B; the natural environment is always optimized so any change (e.g., blocking the ants from tree A) will reduce the performance of all members of the network C. no change in growth; due to the size difference between the trees and the insects, the presence or absence of insects will not have an effect on tree growth
