What does it mean when some adaptations have better survival value in certain environments?

When some adaptations have better survival value in certain environments, it means that specific traits or characteristics enhance an organism's ability to survive and reproduce in that particular context. These adaptations can provide advantages such as improved foraging efficiency, predator avoidance, or resilience to environmental stresses. As conditions change or differ between habitats, the effectiveness of these adaptations can vary, leading to the natural selection of traits best suited for those specific environments. This process highlights the dynamic relationship between organisms and their ecosystems.
