Which of the following best exemplifies how a species can become endangered?

A species can become endangered through the depletion of natural resources, which directly impacts its survival. When essential resources such as food, water, and habitat are diminished, the species struggles to sustain its population. For instance, if deforestation occurs in an area where a species relies on a specific type of tree for food and shelter, the loss of that resource can lead to a decline in their numbers. Overexploitation of resources, pollution, and climate change can further exacerbate this scenario, pushing a species closer to extinction.

In contrast, geographic isolation could lead to speciation rather than endangerment, as isolated populations may evolve differently. Increased habitat diversity often supports a wider range of species and can promote ecosystem resilience. Adaptive radiation describes the process where organisms diversify rapidly into a range of forms to adapt to different environments, typically following a change in the environment or the colonization of new habitats, which does not directly correlate to species becoming endangered.
