What factors influence the birth rate and death rate of humans?
epidemicsgender (females live longer than males on most occaisions)location (where they live)drugs/alcohol/tobaccogenetics (if someone's parent has a disease, they may get the disease)
What are the factors that affect death rate?
The factors which affect death rate are quality of living; such as, sanitation, dirty water, etc. Other factors are diseases, famine, and where you are born. e.g. if you were born in an LEDC you will have a lower life expectancy than those living in MEDC's due to their good resources, technology and facilities.
What are the causes of population change?
Births and deaths are natural causes of population change. The difference between the birth rate and the death rate of a country or place is called the natural increase. The natural increase is calculated by subtracting the death rate from the birth rate.
How do you compute the natural growth rate of a country?
Subtract the crude death rate from the crude birth rate.Crude birth rate is the number of children born per one thousand people.Crude death rate is the number of people that die per one thousand people.
What is Population Size limited by?
Population size can be limited by factors such as availability of resources (food, water, shelter), predation, competition for resources, disease, and environmental conditions (such as climate and habitat suitability). These factors can influence birth rates, death rates, and migration patterns within a population, ultimately affecting its overall size.
Why don't population grow exponentially?
Because of Limiting Factors (environmental factors that prevent a population from increasing). Biotic Limiting Factors = Living organisms; Abiotic Limiting Factors = Nonliving organisms.Other factors include: Death Rate, Birth Rate, Carrying Capacity, Predation
What is a ecosystem effect?
The effect of the overpopulation's is:Decline in the death raterose of the birth ratemigrationLack of education
Two factors that keep populations stable?
Birth and death.
Birth rates and death rates are factors of a population study.?
Yes. Birth rates and death rates are factors of a population study. True. Easier for people to understand than yes.
What stabilizes a population and its carrying capacity?
Factors such as availability of resources, competition for resources, predation, disease, and environmental conditions can all help stabilize a population and its carrying capacity. These factors work together to regulate population size by balancing birth rates and death rates within the ecosystem. When these factors are in balance, the population is able to stabilize around the carrying capacity of the environment.
What influences birth and death rates?
Birth rate (i) Improvement in health and medical facilities help in increase of birth rate.(ii) Decrease in death rate.Death rate(i) When birth rate decreases death rate increases.
Environmental factors that limit population density is?
Environmental factors that limit population density include availability of resources such as food and water, suitable habitat, climatic conditions, predation pressure, competition for resources, and disease prevalence. These factors play a crucial role in determining the carrying capacity of a given environment for a specific species.
What are two factors where population size can increase?
the main ones are birth and death
What Factors affect population?
Factors that affect population size include birth rates, death rates, immigration, and emigration. Additionally, access to healthcare, socioeconomic factors, education, and environmental conditions can influence population growth or decline. Government policies and urbanization also play a role in shaping population changes.
How will a population change over time?
A population can change over time due to factors like birth rate, death rate, immigration, and emigration. High birth rates can lead to population growth, while high death rates can lead to a decline. Immigration can increase the population, while emigration can decrease it. Environmental factors, public health policies, and socio-economic conditions can also impact population changes.
In a natural community population sizes vary because?
of factors such as competition for resources, predation, disease, environmental conditions, and reproductive rates. These factors interact to influence birth and death rates within the population, leading to fluctuations in population size over time. Additionally, natural events like weather patterns and natural disasters can also impact population sizes.
What is the definition of Environmental factor?
Environmental factors are factors that influence living organisms. This can be a plant, an animal, or a germ. Sunlight, food, water, or pollution are types of environmental factors. They may cause growth, mutations, or death of the organism.
