Habitat limits result in a populations

A)salinity

B) temperature

C) physical obstacles

D) biogeographic range

The correct answer is C) physical obstacles.

Habitat limits can greatly impact the size and distribution of populations. Various factors can act as habitat limits, restricting the growth and expansion of populations. In this case, physical obstacles are the main factor that limits population growth within a particular habitat.

Physical obstacles refer to natural barriers or structures that restrict the movement or expansion of organisms. These obstacles can include mountain ranges, rivers, large bodies of water, dense forests, or any other physical features that pose a challenge for species to cross or occupy.

Physical obstacles can limit population growth by preventing organisms from accessing essential resources such as food, water, or suitable nesting sites. They can also impede the movement of individuals between different areas, hindering gene flow and reducing genetic diversity.

Furthermore, physical obstacles can create fragmented habitats, isolating populations and reducing their overall size. Smaller populations are usually more vulnerable to threats like predation, disease, or environmental fluctuations, which can further impact their growth and survival.

In summary, physical obstacles act as habitat limits by impeding the movement, dispersal, and expansion of populations, ultimately affecting their size and distribution.
