Question

Aphids can feed in the leafy treetops (or tree canopies). Ants are usually not abundant in the tree canopies unless aphids are also present. You introduce aphids to an area of the tree canopy and survey the abundance of ants over time.

A. True
B. False

1. The best control for your experiment in the question directly above is a tree in which you add a second ant species and you measure the abundance of the first ant species over time.
2. You continue yor experiments by taking one of the trees in the canopy and removing all of the ants. If the ants and aphids are in a mutualistic relationship that strongly benefits them both, you expect the aphid population will decrease in size in response to the lack of ants.
3. You would expect ant abundance to decrease over time.
Please help, thanks!!!
