What Are The Factors That Affect Population Distribution?

Why is random distribution so rare?

Random distribution is rare in nature as biotic factors, such as the interactions with neighboring individuals, and abiotic factors, such as climate or soil conditions, generally cause organisms to be either clustered or spread apart..

What is the main cause of population growth?

Reasons for the expected population growth include increase in the number of young unmarried mothers, high fertility rates for some ethnic groups, and inadequate sexual education and birth control provision.

Can environmental factors affect the population growth and size?

Environmental factors do affect a population’s growth rate, however. The interaction of the population’s natural growth rate and the environment determines the density of the surviving population. The maximum number of individuals that a given environment can support is called the carrying capacity.

What are the two types of population distribution?

The organisms in a population may be distributed in a uniform, random, or clumped pattern. Uniform means that the population is evenly spaced, random indicates random spacing, and clumped means that the population is distributed in clusters.

What are the five factors that affect population?

Factors influencing population growthEconomic 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.More items…•

What are the 4 factors that affect population growth?

Population growth rate is affected by birth rates, death rates, immigration, and emigration. If a population is given unlimited amounts of food, moisture, and oxygen, and other environmental factors, it will show exponential growth.

What are the 3 types of population distribution?

Individuals of a population can be distributed in one of three basic patterns: they can be more or less equally spaced apart (uniform dispersion), dispersed randomly with no predictable pattern (random dispersion), or clustered in groups (clumped dispersion).

Which factors affect the population distribution of southern Africa?

1. Physical Factors: Physical factors that affect population distribution include altitude and latitude, relief, climate, soils, vegetation, water and location of mineral and energy resources.

What are the two important factors that affect human population growth?

Factors affecting populations. Populations are affected by many factors, the main natural ones being birth rates and death rates which affect the level of natural change (increase or decrease) within the population.

What factors affect animal population?

In the natural world, limiting factors like the availability of food, water, shelter, and space can change animal and plant populations. Other limiting factors, like competition for resources, predation, and disease also impact populations.

What is the most common type of population distribution?

Clumped distributionClumped distribution is the most common type of dispersion found in nature. In clumped distribution, the distance between neighboring individuals is minimized.

What are two things that decrease a population?

The two factors that decrease the size of a population are mortality, which is the number of individual deaths in a population over a period of time, and emigration, which is the migration of an individual from a place.

What are 3 factors that limit population growth?

In the natural world, limiting factors like the availability of food, water, shelter and space can change animal and plant populations. Other limiting factors, like competition for resources, predation and disease can also impact populations.
