Which factor influences the size of the home range?

• A. Weather and Diet
• B. Color of fur and Age
• C. Size, Age, and Behavior
• D. Size and Weather

Answer: (C)

Home range size is shaped by how much energy the animal needs and how it behaves socially and ecologically. A bigger animal generally requires more food and resources, so its range tends to be larger to meet those needs. Age matters because juveniles are often in dispersal or learning phases, which can lead to smaller or expanding ranges, while adults may have established territories or different movement patterns that influence the size of the area they use. Behavior is key: solitary or territorial species usually regulate a defined area, whereas social, roaming, or migratory species cover larger or seasonal ranges. Weather can affect day-to-day activity but doesn’t set the overall range size, and diet affects what resources are used within the range rather than its extent. Color of fur has no bearing on range size. Therefore, Size, Age, and Behavior best explain why home range size varies.
