Why is the golden-winged warbler's low population concerning for its survival?

It may lead to extinction due to lack of diversity
Increased competition for food sources
It attracts more predators
Global warming may affect their habitat

The correct answer is: It may lead to extinction due to lack of diversity

The concern regarding the golden-winged warbler's low population is primarily related to its reduced genetic diversity, which is crucial for the survival of any species. When a population shrinks, it can lead to inbreeding, where genetically similar individuals reproduce. This decreases genetic variation, making the population more vulnerable to diseases and environmental changes. Low genetic diversity can hinder adaptability to changing conditions and reduce overall fitness, which could ultimately lead to extinction. While increased competition for food sources, attraction of more predators, and the impact of global warming on their habitat are valid ecological concerns, they do not directly address the genetic and evolutionary challenges that a low population size brings. These factors, while significant, are secondary to the fundamental issue of survival that is impacted by genetic diversity.
