Final answer:
Competition with invasive species in human populations can increase extinction rates. The red fire ant is an example of an invasive species that competes with native ant species. Human activities contribute to the introduction and spread of invasive species, leading to their competitive advantage and the decline or extinction of native species.
Step-by-step explanation:
Competition with invasive species can increase in human populations and lead to an increase in extinction rates. One specific example is the red fire ant, which is an invasive species that competes with native ant species for resources. The red fire ant has spread rapidly across different regions, displacing native ant populations and causing their decline or extinction.
As human populations expand and encroach on natural habitats, they unintentionally introduce invasive species through trade and travel. These invasive species often have advantages over native species, such as competitive traits or no natural predators, which allow them to outcompete and displace native species. This increased competition can lead to the decline or extinction of native species, as they are unable to effectively compete for resources.
In addition to direct competition, invasive species can also disrupt ecosystems and impact the survival of native species indirectly. For example, invasive plants may alter the habitat structure or nutrient availability, negatively affecting native flora and fauna.
