Disruptive selection
Natural selection . Stabilizing selection
. Directional selection
the answer is one of these idk which one
decrease
Scarcity
deforestization or the destruction of owl habitats could cause a decrease in an owl population. This would then mean the owls prey, such as a field mouse, would flourish and increase in population.
I think Population.
If the limiting factor chosen is food scarcity, the pigeon population in the town could decrease due to increased competition for limited food resources. This could lead to malnutrition and reduced reproductive success among the pigeons, ultimately resulting in a decline in their population.
Competition
water scarcity in tamilnadu is all because of over population,lack of water management,pollution,climate changes,etc
If the supply decrease and demand is constant, it will result into higher prices for the good. Ideally, this will automatically make the demand higher than market supply which creates scarcity.
Analyzing the Thomas Malthus graph can provide insights into the relationship between population growth and resource scarcity. The graph illustrates Malthus' theory that population tends to grow exponentially while resources grow linearly, leading to potential scarcity and challenges in sustaining the population. This analysis highlights the importance of managing population growth and resource utilization to ensure long-term sustainability.
A population can decrease in size through emigration, which is the movement of individuals out of a population to another area. Another way is through mortality, which is the death rate within a population exceeding the birth rate, leading to a net decrease in population size. These two factors, emigration and mortality, can result in a decline in population numbers over time.
The deer would not have enough food and start to starve to death which would cause the population to decrease locally. They may migrate toward other areas not as impacted by the drought, or spread out more.
Several factors can lead to a decrease in squirrel populations, including habitat loss due to urban development and deforestation, which reduces their living and feeding areas. Increased predation from animals like hawks, owls, and foxes can also impact their numbers. Additionally, disease outbreaks and harsh weather conditions can significantly affect their survival rates and reproduction. Lastly, food scarcity during winter months can contribute to population declines.
