How may the inability of a species to adapt within change environment contribute extinction that species?

The inability of a species to adapt within a changing environment can significantly contribute to its extinction. Here's how it occurs:

1. Lack of Genetic Variation: Adaptation relies on genetic variation within a population. If a species has low genetic diversity, it may lack the necessary genetic traits to respond to environmental changes. Without the ability to evolve and adapt, the species becomes vulnerable to changing conditions.

2. Environmental Mismatch: As the environment changes, the species' habitat, food sources, predators, and other ecological factors may shift. If the species cannot adapt quickly enough to these changes, it may find itself in an environment that no longer suits its needs. This environmental mismatch can lead to population decline and eventual extinction.

3. Competition and Resource Scarcity: Environmental changes can alter resource availability and intensify competition with other species. If a species cannot adapt to changing resource conditions or compete effectively with other species, it may face reduced access to food, shelter, and other resources necessary for survival. This can lead to population decline and increased risk of extinction.

4. Disease and Parasite Susceptibility: Changing environmental conditions can also affect the prevalence and impact of diseases and parasites. Species that are unable to adapt to new pathogens or parasites may experience increased susceptibility, leading to population declines and increased risk of extinction.

5. Habitat Loss and Fragmentation: Environmental changes, such as climate change, deforestation, and urbanization, can lead to habitat loss and fragmentation. If a species' habitat is significantly reduced or fragmented, it may become unable to find suitable areas for breeding, feeding, and other essential activities. This can lead to population decline and, ultimately, extinction.

6. Reduced Reproductive Success: Environmental changes can disrupt the reproductive cycle of a species. For example, changes in temperature, rainfall, or food availability may affect mating behaviors, breeding success, and the survival of offspring. If reproductive success declines significantly, it can lead to population decline and an increased risk of extinction.

In summary, the inability of a species to adapt to environmental changes can have severe consequences, leading to population decline and the potential for extinction. Adaptation is crucial for the long-term survival of species and their ability to thrive in a dynamic and changing environment.
