What will most likely occur if population density increases in a population that is density-dependent?
The correct option isb.
In a density-dependent population, the birth rate will increase, if population density…
What limiting factors affect human population?
All living populations possess a tendency for growth. Simultaneously, these populations encounter limitations to that potential. Some factors affecting human population growth (and other organisms’ population growth) include predation, disease, scarcity of vital resources, natural disasters and an inimical environment.
What is the difference between a density dependent and a density independent abiotic factor?
a. Density independent abiotic factors depend on the number of individuals in a population, whereas density dependent do not. … Density dependent abiotic factors affect populations relative to their population size and can involve resource shortages that push a population beyond its carrying capacity.
Which of the following is an example of a density dependent effect on a population quizlet?
Examples of density-dependent factors that affect population growth include predation, disease, and competition.
Which of the following is an example of a density-dependent limitation on a population?
Density-dependent limiting factors tend to be biotic—having to do with living organisms. Competition and predation are two important examples of density-dependent factors.
Do abiotic factors exert a density-dependent or a density independent effect on a population?
Density-dependent regulation can be affected by factors that affect birth and death rates such as competition and predation. Density-independent regulation can be affected by factors that affect birth and death rates such as abiotic factors and environmental factors, i.e. severe weather and conditions such as fire.
What does independent factor mean?
It is a variable that stands alone and isn’t changed by the other variables you are trying to measure. For example, someone’s age might be an independent variable. Other factors (such as what they eat, how much they go to school, how much television they watch) aren’t going to change a person’s age.
How will its rate of growth affect its population density?
To assess a population’s growth rate, an ecologist must know how many individuals are born, how many died, and how many move away in a given period of time. What else must an ecologist know? A population’s emigration in one month totaled three individuals. During the same period, immigration was 17 individuals.
What is density dependence and why is it important in multicellular organisms?
In macroparasite (multicellular organisms) life cycles, positive density-dependence indicates a situation where population growth is facilitated by increased population density. … Density-dependent processes are responsible for influencing parasite fecundity, survival, and establishment in macroparasite life cycles.
What are the 4 factors that affect population growth?
Population growth rate is affected by birth rates, death rates, immigration, and emigration.
Is density size dependent or independent?
Density is the mass per unit volume of a substance. Like melting point and boiling point, density is a size-independent property.
