How do parasites serve as a density dependent limiting factor?
Parasites can limit the growth of a population. They take nourishment from their hosts, often weakening them and causing disease or death. As the population of parasites grow, the population of their hosts tend to decrease.
How are birth rates and death rates used to measure population growth?
they indicate how many people are born verses how many die. more born than dead = population growth more dead than born= popultation decrease
How does the birth rate compare to the death rate of a population whose size remains constant?
The difference between the two is 'population growth' if it is a positive number or 'population decline' if it is negative.
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.
Why did the population grow slowly for most of human existence?
Birthrates, Death Rates, and the age structure of a population help predict why some countries have high growth rates while other countries grow more slowly.
What happens to population growth if the death rate is higher than the birth rate?
The population growth will decline since more people are dying then being born subject to condition that migration factor remains constant
List 4 contributing factors that affect population?
Birth rate: The number of births per 1,000 people in a given population affects its growth rate. Death rate: The number of deaths per 1,000 people can impact the population size and structure. Immigration: The movement of people into a population can increase its size and diversity. Emigration: The movement of people out of a population can decrease its size and potentially impact its workforce and demographics.
How do the concepts of birthrate and population growth differ?
Birthrate is how many people are born, while the population growth includes the death rate as well. If the birthrate minus the death rate is positive then the population growth is +. If it is negative there is a decrease in population (the population is - ). The population growth also takes emigation and immigration into the picture.
Zero population growth is a characteristic of what growth?
Zero population growth is a sign of a low birthrate. Other factors that affect population growth include a stagnant Death Rate and a low mortality age.
How do parasites serve as a density dependent limiting factor?
Parasites can limit the growth of a population. They take nourishment from their hosts, often weakening them and causing disease or death. As the population of parasites grow, the population of their hosts tend to decrease.
How does parasites serve as a density-dependent limiting factor?
Parasites can limit the growth of a population. They take nourishment from their hosts, often weakening them and causing disease or death. As the population of parasites grow, the population of their hosts tend to decrease.
How do demographers figure out population growth.?
Demographers figure out population growth by comparing birth rates and death rates.
Relationship between birth rate death rate and growth rate?
the birth rate is the rate of birth in a population, the death rate is the number of deaths in a population and the growth rate is the growing numbers of the population.
What major effect has global population growth had?
death disease
Effects of population growth?
Overcrowding, pollution, starvation, death.
What impact did the black death have on eroupe?
it had an impact on the population growth
Why are earthquakes a density independent factor limiting human population growth?
Earthquakes causes death of organisms despite the numbers present in the population. Hence it is an density independent factor. The impact of the earthquake is the same even if the population is 100 or 1000. It also does not depend on whether the organisms possess traits that aid in their survival.
