29 to 33 please

Answer 1

Answer. 29 D) both A and C are correct because in density dependent factor are those factor where the growth or population size vary on the population density.

Answer 30. D = 1- { $\sum$ n(n-1)/N(N-1)}

Where n = total number of organism of a particular species

N = total number of organism of all species.

N(N-1) = 100 (99) = 9900

$\sum$ n(n-1) = 3770

D = 1- ( 3770/9900) = 1- 0.387 = 0.613.

Answer 31. Character displacement is the result of interspecific competition

Answer 32 D)/ no two species can exist for long on the same limiting resource.

Answer 33. Pioneer species may modify the environment and permit the establishment of later successional species.
