Answer:
See the answer below
Step-by-step explanation:
A) The ultimate determinant of dispersion pattern a species would exhibit is the kind of relationship it shares with other species within the population and the abiotic factors of the environment such as food availability. A species would want to move far away from a predating species as much as possible, for example.
B) The type of dispersion pattern that is rarest in nature is uniform dispersion. This is because biotic and abiotic factors generally determine the dispersion pattern of species and these factors are rarely uniformly distributed in the environment themselves.
