What is the main properties used to describe a population?
The three main properties of a population are Population size(number of individuals in an area), density(the number of individuals per unit or volume), and dispersion(the arrangement of its individuals).
Which of the following is one of the main properties used to describe a population group of answer choices?
Chapter Eight Review
| Question | Answer |
|---|---|
| The average age at which members of a species reproduce is called | generation time |
| The maximum number of offspring that each member of a population can produce is called the | reproductive potential |
| The three main properties used to describe a population are | size, density, dispersion |
What is the method of determining population size?
mark-recapture method
For organisms that move around, such as mammals, birds, or fish, a technique called the mark-recapture method is often used to determine population size. This method involves capturing a sample of animals and marking them in some way—for instance, using tags, bands, paint, or other body markings, as shown below.
What type of growth can occur if a population has plenty of food and space and has no competition or predators?

|---|---|
| The three properties of populations. | Size, density and dispersion. |
| The birth rate minus the death rate. | Growth rate. |
| This type of population growth occurs when there is plenty of food and space, and no competition or predators. | Exponential growth. |
What are the property of population?
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 is an example of a clumped distribution of a population?
Clumped dispersion is seen in plants that drop their seeds straight to the ground, such as oak trees, or animals that live in groups, such as schools of fish or herds of elephants.
Which of the following are properties of populations?
The population has the following characteristics:
- Population Size and Density:
- Population dispersion or spatial distribution:
- Age structure:
- Natality (birth rate):
- Mortality (death rate):
- Vital index and survivorship curves:
- Biotic Potential:
- Life tables:
How does population density differ from population size?
Population size is the number of individuals in a population. Population density is the average number of individuals per unit of area or volume. The pattern of spacing of individuals in a population may be affected by the characteristics of a species or its environment.
What are the 4 methods of determining population size?
Here we compare estimates produced by four different methods for estimating population size, i.e. aerial counts, hunter observations, pellet group counts and cohort analysis.
Which type of growth can occur only when a population?
Figure 1. When resources are unlimited, populations exhibit exponential growth, resulting in a J-shaped curve. When resources are limited, populations exhibit logistic growth.
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.
What is population describe the characteristics of population?
A population is all of one kind of species residing in a particular location. Population size represents the total number of individuals in a habitat. Population density refers to how many individuals reside in a particular area.
