Why did Virginia secede from the Union? Several states in the Deep South, beginning with South Carolina, had already left the Union in response to the election in November 1860 of Abraham Lincoln as United States president. Virginia, however, hesitated, and debate raged on for months.

8 Factors Influencing the Distribution and Density of Population in India Climate is as important as terrain in influencing population. Of all the climatic factors, twin elements of rainfall and temperature play the most important role in determining the population of an area. Man cannot go beyond the limits set by climate. Extremes of climate discourage the concentration of population.

- Factors that cause population growth include increased food production, improved health care services, immigration and high birth rate. These factors have led to overpopulation, which has more negative effects than positive impacts. Keep Learning.

How Many People Can Earth Support? According to population biologist Joel Cohen of Columbia University, other environmental factors that limit the Earth's carrying capacity are the nitrogen cycle, available quantities of phosphorus, and atmospheric carbon concentrations, but there is a great amount of uncertainty in the impact of all of these factors.

- Two density-independent limiting factors include temperature and weather. These two factors do not rely on the size or density of a certain population. They affect all organisms (in a population) equally.f the population density in the ecosystem were to increase, competition over these cacti would increase, making this a density-dependent limiting factor. Only a certain density of Cactus Wren can be supported in an ecosystem. Another example of a density-dependent limiting factor is disease.

Biomes is an excellent example, they are a large unit organization that are categorized into regions of the Earth’s ecosystem.

Density Dependent Limiting Factors Density Dependent Limiting Factors. The density dependent factors are factors whose effects on the size or growth of the population vary with the population density. There are many types of density dependent limiting factors such as; availability of food, predation, disease, and migration.However the main factor is the availability of food.ike density dependent limiting factors, the independent factor of death valley affects the population of the living things as well. However this time the factors are more Abiotic rather than biotic thing. For example in death valley one of the independent factors is natural disasters like flash flooding.

8.5 Biotic and Abiotic Limiting Factors Abiotic Limiting Factors. Abiotic limiting factors include light, water, nutrients or minerals, oxygen, the ability of an ecosystem to recycle nutrients and/or waste, disease and/or parasites, temperature, space, and predation.

Human Let's review populations, which are a group of individuals of the same species that inhabit the same area, and the factors that influence changes in populations. Over time, the human population has increased, which results in a positive population growth rate, which is the rate at which the population changes in size.

Biliary Duct Obstruction A cholecystectomy is the removal of the gallbladder if there are gallstones. An ERCP may be sufficient to remove small stones from the common bile duct or to place a stent inside the duct to restore bile flow.

- Making the world better, one answer at a time. Well the carrying capacity is the maximum number of individuals of a particular species that a particular environment can take, then it works to stabilize that population.So adding a limiting factor would stabilize the populations size more.imiting factors limit the population from increasing. carrying capacity is the maximum amount of organisms that can live in an area. 1.Sources of food supply 2.Prey and predator 3.Human activity 4.Etc. + 88 others found this useful.

- The separate populations over time may evolve distinctly different characteristics. If the geographical barriers are later removed, members of the two populations may be unable to successfully mate with each other, at which point, the genetically isolated groups have emerged as different species.Allopatric isolation is a key factor in speciation and a common process by which new species arise.ortions of a populations that exist along the edges of the parent population's geographic territory have higher likelihood of developing reproductive isolation. Such peripheral populations are likely to possess genes that are different from the parental population.

Biotic and Abiotic Factors Influence on Ecosystems Biotic and Abiotic Factors Influence… Both abiotic and biotic factors determine both where an organism can live and how much a population can grow. A limiting factor is a factor that restricts the size of a population from reaching its full potential. The amount of food & water in a habitat is an example of a limiting factor. Other factors include geographical space, predation, climate, competition (for prey, food, mates) etc.

Limiting Factors Limiting Factors. Edit 0 4 …. Limiting Factors A limiting factor is a factor (abiotic and biotic) that decreases population size. There are two types of limiting factors: Density-Independent-Limiting factor that affects population regardless of size.n the tropical savanna, some factors are lack of rainfall and lightning-set fires. During the rainy season, fires set by lightning storms kill tree seeds. If this did not happen, the savanna would turn into a tropical dry forest. Density-Dependent-Limiting factor that depends on population size.

Density-Dependent Factors: Examples & Definition There are several types of density-dependent factors, but they all have two things in common: they influence the rates of births and deaths, and the effect increases as population size increases. When the density of a population is low (few individuals in a given area), resources are not limiting. There are plenty of resources for everyone. More individuals can give birth, and fewer individuals will die. Overall, the population will grow in size and become denser.

Density-independent factor In population ecology: Factors affecting population fluctuation …of populations into density-dependent and density-independent factors. Density-independent factors, such as weather and climate, exert their influences on population size regardless of the population’s density. In contrast, the effects of density-dependent factors intensify as the population increases in size.

Limiting Factors In the context of populations, a limiting factor is a factor that causes population growth to decrease. Density-Dependent Factors Density-Dependent Factors A limiting factor that depends on population size is called a density-dependent limiting factor. Density-Dependent Factors Density-dependent limiting factors include: • competition • predation • parasitism • disease Density-Dependent Factors Density-dependent factors operate only when the population density reaches a certain level. These factors operate most strongly when a population is large and dense. They do not affect small, scattered populations as greatly. Density-Dependent Factors Competition When populations become crowded, organisms compete for food, water space, sunlight and other essentials. Competition among members of the same species is a density-dependent limiting factor. Density ...

predisposing factor Any social (e.g., domestic violence), economic (e.g., poverty), biological (e.g., breast cancer gene), behavioural (e.g., smoking) or environmental (e.g., air pollution) factor that is associated with—but does not independently cause—an increased risk of a particular disease, injury or physical or mental illness.

What are examples of density-independent factors? Density-Independent Factors. Weather, climate, and natural disasters such as freezes, seasonal changes, hurricanes, and fires are examples. These factors are unrelated to population size and affect everyone in the population regardless of population size. Based on the list all are density dependent. Density Dependent Factors. Increasing population size reduces available resources limiting population growth. In restricting population growth, a density-dependent factor intensifies as the population size increases, affecting each individual more strongly. Population growth declines because of death rate increase, birth rate decrease or both.
