Question

Quizplus · Accepted Answer

Statement I is true as dispersal is a common strategy used by both plants and animals to expand their ranges and colonize new habitats. 
Statement II is not entirely accurate as while climate may play a role in colonization, dispersal mechanisms such as wind or animal transport are also important factors. 
Statement III is true as seeds are a common dispersal stage in flowering plants. 
Statement IV is false as dispersal can occur over short time scales as well, such as when animals migrate to different areas in search of food or mating opportunities.
