Finally, you take a tree and block the ants from the canopy. Then you spend three years counting the number and types of insects on the forest floor around this tree (tree A) and in the area around a tree in which ants are not blocked (tree B)
You find that the area around
tree A has 25% fewer ants and 40% more beetles than the area around tree B. These data
support the hypothesis that:
A. there is no relationship between ant
abundance and beetle abundance.
B. there is a positive relationship between ant
abundance and beetle abundance.
C. there is a negative relationship between
ant abundance and beetle abundance.
D. ecological interactions in the tree canopy
have no effect on forest floor communities.
E. ecological interactions in the tree canopy
always have a negative effect on forest floor
communities.
