Considerable evidence indicates that the null model of community structure is incorrect because
A)each species responds independently of other species to the prevailing physical environment.
B)interactions among species have no significant influence on community structure.
C)when one species is removed,the populations of the other species are unaffected.
D)species interactions modify the fundamental niche of the species involved,influencing their relative abundance and,in some cases,their distribution.

Question

Quizplus · Accepted Answer

The option D is correct as the null model of community structure assumes that species interact independently with the physical environment and each other. However, considerable evidence shows that species interactions modify the fundamental niche of the species involved, and this influences their relative abundance and distribution. Therefore, the null model is incorrect because species interactions have a significant influence on community structure. Options A, B, and C are incorrect because they all contradict the evidence of species interactions affecting community structure.
