What factors will have a greater impact on a population as the density of that population increases?
A natural disaster will have a greater impact on a population as the density of that population increases. A natural disaster will have a greater impact on a population as the density of that population increases.
What major factor has the greatest effect on population density?
Fertile land attracts a higher population density as food can be produced. A reliable water supply encourages a high population density as water can be used for drinking, washing, transportation and irrigation.
Which factors increase the density of a population?
Density dependent factors include the environmental resources needed by the individuals of a population. Competition for food, water, shelter, etc., results as the population density increases.
What factors can impact the population size of a species?
Nutrition is also one factor in how big or small a whole population of animals can get, not just individuals within that population. Other factors that influence animal population size include water, habitat, competition, predation, and lots more.
Is a high population density good?
And cities with large, densely-packed populations are often epicenters of economic growth, the arts, and tourism. Higher-density cities definitely do bring their own benefits and negative consequences. But if city officials are prepared, they have the ability to do more good than harm.
What is considered a high population density?
Population density is the average number of people living per square mile/km. A high population density implies that the population is high relative to the size of the country. Countries, such as Belgium and the Netherlands have a high population density.
What are the problems in areas of high population density?
There will be an increase in land degradation by building houses and flats which makes land pollution, water contamination by a huge volume of people makes water pollution, and massive usage of vehicles will contribute to air pollution. These areas will lack the storage facility for water because of high density.
Which country has the highest density of population?
Of the larger countries1, Bangladesh is the most densely-populated with 1,252 people per square kilometer; this is almost three times as dense as its neighbour, India. It’s followed by Lebanon (595), South Korea (528), the Netherlands (508) and Rwanda (495 per km2) completing the top five.
What are the factors affecting population growth?
Factors influencing population growth
- Economic development.
- Education.
- Quality of children.
- Welfare payments/State pensions.
- Social and cultural factors.
- Availability of family planning.
- Female labour market participation.
- Death rates – Level of medical provision.
Why is high population density bad?
Previous studies have shown that population density may be a double-edged sword to residents’ health in developing countries. On the one hand, high population density is normally associated with poor sanitation, shortage in public facilities and services, and environmental degradation [11].
Which Two factors determine the size of a population?
Population Growth Rate The two main factors affecting population growth are the birth rate (b) and death rate (d). Population growth may also be affected by people coming into the population from somewhere else (immigration, i) or leaving the population for another area (emigration, e).
What are the three main factors that affect a population?
Three primary factors account for population change, or how much a population is increasing or decreasing. These factors are birth rate, death rate, and migration.
Which two factors can both cause a population to increase birth rate and emigration birth rate and immigration?
The right option is; birth rate and immigration Increased birth rate and increased immigration rate can both cause a population to increase.
What are the factors that affect the population growth rate?
Although there are factors that either increase or decrease the human population, when these factors are combined, they represent the overall population growth rate. The population growth rate is the rate at which the population changes in size.
Which is an example of density independent factor?
These names mean just what they say: Density-independent factors have an impact on the population, whether the population is large or small, growing or shrinking. For example, a wildfire that sweeps through a dense forest in the Everglades has a big impact on every population in the community, regardless of the density of any one population.
Why do some areas have higher population density than others?
Areas with few resources tend to be sparsely populated e.g. The Sahel Unstable countries tend to have lower population densities as people migrate e.g. Afghanistan. Good job opportunities encourage high population densities, particularly in large cities in MEDCs and LEDCs around the world. Further reading: What causes population change?
Is the population growth rate positive or negative?
The population growth rate can result in either a positive or negative rate depending on the factors. Let’s review populations, which are a group of individuals of the same species that inhabit the same area, and the factors that influence changes in populations.
What are the factors that affect population growth?
Key points 1 In nature, population size and growth are limited by many factors. 2 Density-dependent limiting factors cause a population’s per capita growth rate to change—typically, to drop—with increasing population density. 3 Density-independent factors affect per capita growth rate independent of population density.
What happens when you have a higher population density?
But when you are traveling alone at night, having a higher population density makes it more likely to have people in the vicinity, which lowers your chances of being mugged. There tends to also be a stronger tax base, allowing for more police who simultaneously have less area to patrol.
Which is an example of a density dependent factor?
Density-dependent limiting factors cause a population’s per capita growth rate to change—typically, to drop—with increasing population density. One example is competition for limited food among members of a population. Density-independent factors affect per capita growth rate independent of population density.
How does density affect the number of predators?
Predation. Higher-density populations may attract predators who wouldn’t bother with a sparser population. When these predators eat individuals from the population, they decrease its numbers but may increase their own. This can produce interesting, cyclical patterns, as we’ll see below.
