What characteristic of a population increases with plentiful resources a population density B spatial distribution C range D clumping?
The correct answer is (A) Population density.
What are the 3 types of population growth?
Population Growth
- An exponential growth pattern (J curve) occurs in an ideal, unlimited environment.
- A logistic growth pattern (S curve) occurs when environmental pressures slow the rate of growth.
Is density a characteristic of population?
The number of individuals living within that specific location determines the population density, or the number of individuals divided by the size of the area. Population density can be used to describe the location, growth, and migration of many organisms.
Which factor will increase a population’s size?
The two factors that increase the size of a population are natality, which is the number of individuals that are added to the population over a period of time due to reproduction, and immigration, which is the migration of an individual into a place.
What is clumped distribution?
Clumped distribution, also called aggregated distribution, clumped dispersion or patchiness, is the most common type of dispersion found in nature. In clumped distribution, the distance between neighboring individuals is minimized.
What is clumped dispersion?
Clumped dispersion (Figure 1) where individuals are aggregated in certain areas of the sampled space. Uniform dispersion (Figure 2), where individuals are almost equally spaced apart from each other and random dispersion (Figure 3).
What causes rapid population growth?
Several factors are responsible for the rapid growth: a drop in mortality rates, a young population, improved standards of living, and attitudes and practices which favor high fertility.
What are the 4 factors that affect population growth?
When demographers attempt to forecast changes in the size of a population, they typically focus on four main factors: fertility rates, mortality rates (life expectancy), the initial age profile of the population (whether it is relatively old or relatively young to begin with) and migration.
What are characteristics of population growth?
They are described by characteristics that include: population size: the number of individuals in the population. population density: how many individuals are in a particular area. population growth: how the size of the population is changing over time.
What are population characteristics?
Demography is the study of a population, the total number of people or organisms in a given area. Understanding how population characteristics such as size, spatial distribution, age structure, or the birth and death rates change over time can help scientists or governments make decisions.
Which of the following increases a population?
Immigration is the movement of individuals into an area and emigration is movement of individuals out of an area. Therefore, natality and immigration will increase population.
What are two things that increase a population?
Populations gain individuals through births and immigration. They lose individuals through deaths and emigration. These factors together determine how fast a population grows.
What is dispersed population?
The dispersion pattern (distribution pattern) of a population describes the arrangement of individuals within a habitat at a particular point in time, and broad categories of patterns are used to describe them.
What is spatial distribution of population?
Population distribution denotes the spatial pattern due to dispersal of population, formation of agglomeration, linear spread etc. Population density is the ratio of people to physical space. It shows the relationship between a population and the size of the area in which it lives.
What is aggregated dispersion?
Aggregated dispersion (also called a contagious or clumped distribution or underdispersion) occurs either when individuals tend to be attracted to (or are more likely to survive in) particular parts of the environment, or when the presence of one individual.
What are the Effects of population growth on natural resources?
Rapid population growth continues to be a major underlying force of environmental degradation and a threat to sustainable use of natural resources. It reduces the quality and quantity of natural resources through overexploitation, intensive farming and land fragmentation.
What happens when population increases?
With population expanding at such a rapid pace, the world will eventually become overcrowded. Population density will increase and global warming, rising tides and increased severity of weather will cause the amount of viable land to decrease.
Why does population increase?
The unprecedented growth of the global population that has occurred since 1950 is the result of two trends: on the one hand, the gradual increase in average human longevity due to widespread improvements in public health, nutrition, personal hygiene and medicine, and on the other hand, the persistence of high levels of …
What are the main characteristics of a population?
Population Characteristics: 5 Important Characteristics of Population
- Population Size and Density: Total size is generally expressed as the number of individuals in a population. …
- Population dispersion or spatial distribution: …
- Age structure: …
- Natality (birth rate): …
- Mortality (death rate):
Why is our population increasing?
This dramatic growth has been driven largely by increasing numbers of people surviving to reproductive age, and has been accompanied by major changes in fertility rates, increasing urbanization and accelerating migration. These trends will have far-reaching implications for generations to come.
What are the characteristics of population growth?
They are described by characteristics that include: population size: the number of individuals in the population. population density: how many individuals are in a particular area. population growth: how the size of the population is changing over time.
Which of the following are the characteristics of expanding population?
The population has the following characteristics:
- Population Size and Density: Total size is generally expressed as the number of individuals in a population. …
- Population dispersion or spatial distribution: …
- Age structure: …
- Natality (birth rate): …
- Mortality (death rate):
What is dispersion in population characteristics?
The dispersion pattern (distribution pattern) of a population describes the arrangement of individuals within a habitat at a particular point in time, and broad categories of patterns are used to describe them. The three dispersion patterns are clumped, random, and uniform (figure 5.1. a).
What is a clumped population?
Clumped dispersion is when individuals in a population are clustered together, creating some patches with many individuals and some patches with no individuals. In uniform dispersion, individuals are spaced evenly throughout an area. And in random dispersion, individuals are arranged without any apparent pattern.
How do natural resources affect population distribution?
The availability of natural resources encourages a higher population density as these can be processed and used in industry and manufacturing. Regions that experience no or few natural disasters are more likely to have a lower population density as they are safer.
How is population distribution connected to resources?
Since resources are not evenly distributed across the globe, this means locations with favorable climates and abundant resources are more densely populated while those with less favorable climates and fewer resources are sparsely populated.
What is clumped population distribution?
Clumped patterns usually occur when resources are concentrated in small areas within a larger habitat or because of individuals forming social groups. At large spatial scales most organisms appear to have clumped distributions because their habitats are not uniformly distributed over wide areas.
What is dispersion in the context of distribution of plants on the landscape?
In the context of this study, dispersion refers to the distance between plants of the same species, while interspersion refers to the degree of intermixing between plants of two distinct species.
How has the increase in population increases the demand for natural resources?
Explanation: Generally speaking, as the human population grows, our consumption of natural resources increases. More humans consume more freshwater, more land, more clothing, etc.
What is the relationship between population growth and resources?
Population and resources have a strong relationship with one another. The growth and decline of population affects the availability of natural resources. At the same time, the availability of natural resources affects the trends seen in population.
