5.Three species A, B and C are found on an
island. When C is artificially removed
the niche of A expands, but that of B does not show any significant
differences. If C is replaced and B is
removed both A and C show some niche expansion, although that shown by A is
larger than that shown by C.
a. What can
you conclude about the interactions between species A B and C on the island? (Explain your reasoning)
If it shows that A expands when C is removed, then it is obvious that A was being consumed by species C. When B was removed and A and C expanded, although A more so that C, it can be concluded that species B was consuming species C. So the chain would go B, then C, then A.
