A group of individuals of a single species that occupy the same general area.
-
A set of characteristics that two different species have in common.
-
None of the Above
Correct Answer
A. A group of individuals of a single species that occupy the same general area.Explanation
The correct answer is "A group of individuals of a single species that occupy the same general area." This definition accurately describes what a population is - a group of individuals of the same species that live in the same geographical location. It distinguishes populations from other options such as a group of individuals who are all types of species in the world or a set of characteristics that two different species have in common, which do not accurately define a population.Rate this question:

-
Organisms that are part of the type II survivorship curve
-
Organisms in the type I survivorship curve.
-
Organisms that can take some advantage of their environment.
Correct Answer
A. Organisms that can take immediate advantage of favorable conditions.Explanation
Opportunistic life history refers to organisms that have the ability to quickly take advantage of favorable conditions in their environment. These organisms are adaptable and can rapidly reproduce and grow when resources are abundant. They have a short life span and produce a large number of offspring, increasing their chances of survival and successful reproduction. This strategy allows them to maximize their reproductive success in unpredictable or unstable environments.Rate this question:

-
Limiting Factors
-
Depending Factors
-
Equilibrial Life History
Correct Answer
A. Equilibrial Life HistoryExplanation
Equilibrial Life History refers to a pattern of developing and reaching sexual maturity slowly and producing few, well-cared-for offspring. This strategy is typically adopted by organisms that live in stable and predictable environments, where resources are abundant and competition is low. By investing more time and energy into the development and care of their offspring, these organisms increase their chances of survival and reproductive success. This strategy is in contrast to opportunistic life history, where organisms reproduce at a young age and produce many offspring, but provide little parental care.Rate this question:

What is called when a population expands in an ideal, unlimited environment?
-
Population Growth
-
Growth
-
Exponential Population Growth
-
Linear Population Growth
Correct Answer
A. Exponential Population GrowthExplanation
Exponential population growth refers to the rapid increase in the size of a population when it has access to unlimited resources and an ideal environment. This type of growth occurs when the population's birth rate exceeds its death rate, resulting in a continuous and accelerating increase in population size. As the population grows, the rate of growth also increases, leading to a steep upward curve on a population growth graph. This term accurately describes the scenario where a population expands without any limitations or constraints.Rate this question:

What restricts the number of individuals that can occupy a habitat?
-
Carrying Factors
-
Basic Factors
-
Limiting Factors
-
Logistic Factors
Correct Answer
A. Limiting FactorsExplanation
Limiting factors are the factors that restrict the number of individuals that can occupy a habitat. These factors can include availability of resources such as food, water, and shelter, as well as competition for these resources among individuals. Additionally, limiting factors can also include factors such as predation, disease, and environmental conditions like temperature and pH levels. These factors act as constraints on the population size, preventing it from exceeding the carrying capacity of the habitat.Rate this question:
-
- 12.
Define Carrying Capacity.
-
The minimum population size that a particular environment can sustain.
-
The maximum amount of resources an environment can sustain.
-
The minimum amount of resources that Earth can have.
-
The maximum population size that a particular environment can sustain.
Correct Answer
A. The maximum population size that a particular environment can sustain.Explanation
Carrying capacity refers to the maximum population size that a particular environment can sustain. It represents the maximum number of individuals that can be supported by available resources such as food, water, and shelter. Once the population exceeds the carrying capacity, resources become limited and can lead to competition, scarcity, and potential population decline. Therefore, the correct answer is the maximum population size that a particular environment can sustain.Rate this question:
-

Which type of growth rate decreases as the population size approaches carrying capacity. Hint the growth rate is zero.
-
Linear Population Growth
-
Logistic Population Growth.
-
Zero Population Growth
-
Ecological Population Growth
Correct Answer
A. Logistic Population Growth.Explanation
Logistic population growth is the correct answer because as the population size approaches its carrying capacity, the growth rate decreases and eventually becomes zero. This is because as the population size gets closer to its maximum sustainable level, resources become limited and competition for those resources increases, resulting in a decrease in the growth rate. Logistic population growth takes into account these limiting factors and models the population growth more accurately than linear population growth or ecological population growth. Zero population growth refers to a stable population size with no net increase or decrease in numbers, which is not applicable in this context.Rate this question:

What type of factor is a population-limiting factor whose effects intensify as the population increases in density?
-
Density Independent Factor
-
Density Dependent Factors
-
Volume Independent Factors
-
Volume Dependent Factors
Correct Answer
A. Density Dependent FactorsExplanation
Density dependent factors are population-limiting factors that have a greater impact as population density increases. These factors include competition for resources, predation, disease, and parasitism. As the population becomes more crowded, there is increased competition for limited resources, making it harder for individuals to survive and reproduce. Predators and diseases also spread more easily in dense populations, leading to higher mortality rates. Therefore, density dependent factors play a crucial role in regulating population size and maintaining ecological balance.Rate this question:

What is it called when there is competition between individuals of the same species for the same limited resources?
-
Inside Competition
-
Competion
-
Population Competition
-
Intraspecific Competition
Correct Answer
A. Intraspecific CompetitionExplanation
Intraspecific competition refers to the competition between individuals of the same species for the same limited resources. This type of competition occurs when individuals within a population compete for resources such as food, water, territory, or mates. It is a common phenomenon in nature and plays a crucial role in shaping the population dynamics and evolutionary processes within a species.Rate this question:

Which type of factor is a limiting factor whose intensity is unrelated to population density?
-
Density Independent Factor
-
Limiting Density Factors
-
Not Density Factors
-
Independent Factors
Correct Answer
A. Density Independent FactorExplanation
A density independent factor is a limiting factor whose intensity is unrelated to population density. This means that regardless of the size or density of a population, this factor will have the same impact. Examples of density independent factors include natural disasters like hurricanes or floods, as well as temperature extremes or pollution. These factors can affect a population regardless of its size, making them independent of population density.Rate this question:

What happens when there is an increases proportion of women of childbearing age in the population?
-
Population Speed
-
Population Control
-
Population Births
-
Population Momentum
Correct Answer
A. Population MomentumExplanation
When there is an increase in the proportion of women of childbearing age in the population, it leads to population momentum. This refers to the continued growth of the population even after fertility rates decline. This is because the larger number of women in their reproductive years means that even with lower fertility rates, there are still more births occurring. This results in a higher population growth rate and momentum.Rate this question:
