The most likely event that led to a sudden decrease in the population of mink in 2010 would be a catastrophic event. The correct option would be B.
Decrease in population
A sudden and sharp decrease in the population of an organism can be caused by a host of factors. These include:
- catastrophic events such as disease outbreaks, natural disasters, famine, etc.
- a sudden appearance of predators in the environment
If the predator has always been in the environment with the population of the organism, this will not result in a sharp decline in the population. A population of predators suddenly joining the environment may be the only cause for a sharp decline in the population of the organism.
