Which variable can heavily influence wildlife population distribution?

The choice that encompasses all variables—elevation, resource availability, and human activity—correctly identifies the comprehensive nature of wildlife population distribution influences. Each of these factors plays a significant role in determining where wildlife can thrive.

Elevation can affect climate, vegetation types, and habitat availability, all of which are critical for different species. For example, certain animals may only inhabit specific altitudes due to temperature variations or food sources available at those heights.

Resource availability, including food, water, and shelter, directly impacts wildlife populations. Species are often concentrated in areas where resources are plentiful, leading to higher densities. Limited resource access can drive populations to migrate or adapt to new areas, thus affecting distribution.

Human activity introduces various pressures, including habitat destruction, pollution, and urban development. These activities can fragment habitats and alter ecosystems, forcing wildlife to adapt or relocate, impacting their distribution significantly.

By recognizing that all these factors interact and influence wildlife habitat preferences and population distributions, the selection highlights the complexity of ecological systems and the myriad influences on wildlife behavior and distribution patterns.
