What is the outcome of eradicating a pest species?

The choice indicating that eradicating a pest species reduces competition for resources is accurate because when a pest is removed from an ecosystem, it diminishes the strain on resources such as food, water, and habitat that other species may rely on. By decreasing competition for these essential resources, native species or economically important species can thrive more effectively, leading to an overall improvement in the health and stability of the ecosystem. This reduction in resource competition can facilitate the recovery and expansion of populations that may have been previously suppressed by the presence of the pest.

In this context, eradicating a pest can lead to a more balanced ecosystem, allowing native species to flourish without the competitive pressure exerted by the invasive pest. As such, the overall dynamics of the ecosystem can shift positively, resulting in healthier populations of native flora and fauna.
