QUESTION 16

The figures show the original distribution zone of Species I and some possible distribution zones of Species I after the introduction of Species II. Species II has a competitive advantage over Species I; however, it does not tolerate areas of lower rainfall.

Biology question figure

Which of the following would be an accurate prediction of the new distribution zone for Species I?

(A) Zone A, i.e. no change to the distribution

(B) Zone B, i.e. reduced distribution within the original zone

(C) Zone C, i.e. new distribution outside the original zone

(D) Zone D, i.e. complete removal of the species from the ecosystem
