Final answer:
Limiting human activities in mulgara habitats is essential for their survival, as this helps maintain ecological balance and minimizes habitat loss.
Step-by-step explanation:
The option that would help ensure the natural survival of the mulgara population is b) Limit human activities in the mulgara habitat. Mulgaras, like many other species, depend on intact ecosystems for their survival. When human activities such as habitat destruction, introduction of invasive species, and habitat fragmentation are limited, it helps maintain the ecological balance necessary for mulgaras to thrive. Conservation efforts should focus on protecting and expanding habitats, limiting disruption from human involvement, and ensuring that habitat loss is minimized. Creating protected areas, minimizing disturbances such as garbage that may attract predators, and managing land use surrounding the habitat are all important measures to ensure the survival of mulgara populations and other wildlife.
