Limiting factors in an ecosystem are environmental conditions that restrict the growth, abundance, or distribution of a particular species. These factors can include availability of food, water, shelter, space, and suitable habitat, as well as competition with other species and predation pressure. When one or more of these factors are in short supply, they can limit the population size and overall biodiversity of an ecosystem.
Without births, the population decrease would be the same as the number of deaths, which is generally between 57-58 million a year.
Oxygen, water, and various types of food are necessary to sustain the human life form.
A limiting factor is a resource or environmental condition that restricts the growth or distribution of a population. When a limiting factor becomes scarce, it can lead to decreased population growth or even population decline as individuals struggle to survive without enough of that resource. This can ultimately impact the overall health and sustainability of the population.
A natural disaster is considered a density-independent limiting factor because its impact on a population does not depend on the population's size or density. Events such as hurricanes, earthquakes, and wildfires can affect large areas and populations regardless of how many individuals are present. This means that even in low-density populations, a natural disaster can cause significant mortality and disruption, leading to a decline in population numbers without being influenced by the population's density.
All species have Limiting Factors. Limiting factors are things that keep an animals population down to its carrying compasity. Limiting factors are space, weather, and food. if there is not enough food animals will die and will not have offspring.Space is limited, without enough space disease spreads quickly and there is no room for nesting or reproducing. weather is a limiting factor because during bad weather, (floods, droughts, winter, etc.) animals will not reproduce, or have offspring, it can also kill off other organisms.

This could be anything, from earthquakes to migration to floods to disease, and so on, and so forth. In nature, population sizes naturally fluctuate even without such events, due to changes in the availability of resources, predation, and so on.
human population has been growing rapidly since before the year 1000 but human population does not have a limit to how high it goes but it's us that gives it a small limit of what it can cope with, food production, waste produce, crime rate, health service are all at risk of over population so the population only has a small limit and we are the only ones that give it the limit!
Population dependent factors become more limiting as the population increases. (eg. amount of resources, intraspecific competition, predation, disease, physiological stress) Population independent factors lower the population size without regards to it. (eg. natural disasters, unnatural weather, acts of fate (volcano, flood, fire, earthquake, hurricane, etc.))
One example of exponential growth and limiting factors is a basic population growth equation, dN/dt=rN(1-N/K), where N(t) is the population at time t, r is the populations growth rate at t=0, and K is the populations carrying capacity which is the limiting factor on the population's exponential growth. The population will increase exponentially until it starts to get close to K at which point the growth rate will slow down and the population will converge to K as t tends to infinity assuming no other factors influence the population. This particular equation is known as a logistic model and in general doesn't represent exponential population growth very well in the real world due to numerous factors such as resources available, other species fighting for the same resources, natural factors such as disease or illness as well as others. This basic model just assumes that a population can grow to a capacity K without interruption and without external effects.
Without births, the population decrease would be the same as the number of deaths, which is generally between 57-58 million a year.

People might use density-independent limiting factors, such as habitat modification or chemical control, to manage populations of introduced species because these methods can have a quick and direct impact on population size. They can help control invasive species that are causing harm to native ecosystems and species. Density-independent factors can be effective in reducing population levels without relying on natural predators or disease.
The best function to model population growth is the exponential growth model, which is commonly represented by the equation P(t) = P0 * e^(rt), where P(t) is the population at time t, P0 is the initial population, e is the base of the natural logarithm, r is the growth rate, and t is time. This model assumes that the population grows without any limiting factors.
carrying capacity is the largest number of individuals of one species that an environment can support. Biotic potential is the potential growth of a population if it could grow in perfect conditions with no limiting factors.
