Famine
An increase in predation pressure or a decrease in food availability are factors most likely to result in a decrease in the size of a specific population. These factors can lead to increased mortality rates and reduced reproductive success, ultimately causing the population to decline in numbers.
An increase in the availability of food, a decrease in predation pressure, or an improvement in reproductive success are factors that can lead to an increase in the size of an animal population.
If all frogs died, the raccoon population would likely decrease due to a loss of a food source. Frogs are an important part of the raccoon's diet, and the lack of this prey could lead to starvation or population decline for raccoons.
As of 2021, Aqa Vali does not have a specific census data available for its population. It is a small rural village in Iran, so its population is likely to be relatively small compared to urban areas.
A decrease in the marsh willow herb population in an area is likely to be caused by environmental changes such as increased water salinity levels, habitat destruction due to human activities, or competition from invasive species that outcompete marsh willow herb for resources. These changes can disrupt the plant's growth, reproduction, and ability to thrive in its habitat.
Increased predation by natural enemies, such as hawks or bobcats, is likely to reduce the carrying capacity of a squirrel population in a forest. By preying on squirrels, these natural enemies can limit their numbers and prevent overpopulation.
Which would most likely decrease the genetic variation in the human population?
