For a species to occupy a unique ecological niche in an ecosystem, the species must interact with other organisms and its environment in a unique way. This unique interaction often involves specific roles in the food web, resource utilization, and environmental interactions that distinguish it from other species.

The mechanism of speciation that might lead to the evolution of new species in habitats that are globally isolated but environmentally similar is allopatric speciation. This occurs when populations are geographically separated, leading to divergence and the formation of new species in isolated environments.

One way geographic isolation can lead to speciation is by preventing gene flow between populations. This isolation allows populations to evolve independently, leading to genetic differences that can eventually result in the formation of new species.

<p>The scenario that exemplifies the impact of geographic isolation on speciation is <strong>a species of fish in a lake split into two populations by a long-lasting drought that creates two smaller lakes</strong>. This geographic isolation can lead to the development of distinct species due to the separation of gene pools and different environmental pressures in each lake.</p> Signup and view all the answers
