Question

which of the following is the most likely cause of extinction for a large population of organisms?
rapid transmission of communicable diseases
demographic variation (random changes in birth or death rates)
density dependent factors known as the \allee effect\
genetic effects (such as inbreeding)
environmental effects (such as global climate change)

Explanation:

For a large population, environmental effects like global climate - change can have far - reaching and long - lasting impacts on habitats, food sources, and overall living conditions, which are more likely to cause extinction compared to the other factors. Communicable diseases may not wipe out a large population as they can be mitigated by natural immunity or adaptation. Demographic variations usually have a smaller impact on large populations. The Allee effect is more relevant to small populations. Genetic effects like inbreeding are less likely to cause extinction in large, diverse populations.

Answer:

Environmental effects (such as global climate change)
