Answer:
C) dwarf mistletoes, which parasitize particular species of forest tree
Step-by-step explanation:
Uniform dispersion is observed in plant species that inhibit the growth of nearby individuals. For example, the sage plant, salvia leucophylla, secretes toxins, a phenomenon called negative allelopathy. Animals that maintain defined territories, such as nesting penguins, also exhibit uniform dispersion.
In lodgepole pine stands, spread of dwarf mistletoe into young trees is more extensive from single, isolated residual trees than from relatively uniform, dense, even-aged stands of residual trees.
