A specialist species has a
wider niche and high efficiency of niche utilization.
narrower niche and high efficiency of niche utilization.
wider niche and low efficiency of niche utilization.
narrower niche and low efficiency of niche utilization.
A specialist species is characterized by having a narrow niche, meaning it has specific requirements and can only thrive in a limited range of environmental conditions or utilize specific resources. Due to its specialized adaptations and behaviors, a specialist species is highly efficient in utilizing its niche. It is well adapted to its specific ecological role, and its traits are finely tuned to exploit a particular set of resources or environmental conditions. This efficiency allows specialist species to excel in their niche but also makes them more vulnerable to changes or disturbances in their habitat compared to generalist species, which have broader niches and greater flexibility in resource utilization. Hence, the correct answer is option 2.
