Limiting Exponential Growth And Logistic Growth Within A Population

1005 Words5 Pages

Introduction
The purpose of this report is to outline major factors limiting exponential growth which leads to logistic growth within a population. And to then show how exponential and logistic growth is relates to the populations growths carrying capacity. Carrying Capacity is the largest size an environment population can support with no net increase over long periods of time. (Wolfe, 2000) When an environment reaches it max, it can show the cause of how a population can reach and oscillate around its carrying capacity. Its relationship to population growth is only to the logistic population growth rate changes as it reaches carrying capacity. (Wolfe, 2000) Logistic population growth rate is one of limited resources for the population in …show more content…

(Campbell & Reece, 2011) It was mention briefly that limiting factors lower the growth of a populations growth rate. Some limiting factors are density dependent and others are density independent. Density-dependent factors include resources such as food or nesting sites and Density- independent factors such as weather influence the population regardless of its size. (Wolfe, 2000) The density of a population isn’t constant and is always changing. Density can increase and decrease over time; adding, and removing individuals from the population. Limiting factors can lower birth rates, increased death rates, or lead to emigration. (Harwood, 2016)) Limiting factor are what cause an increase or decrease of the population density which leads to the population to oscillate around its carrying capacity. Energy, shelter, refuge from predators, nutrient availability, water, and suitable nesting sites can be limiting factors. (Campbell & Reece, 2011) When there is an increase in the populations density, individuals within the population tend to have fewer resources. There is a limit to the number of individuals that can occupy a habitat. (Campbell & Reece, 2011). That is when individual within the population compete for resources and space this causing the growth rate density to stop increasing and the population will level itself. Thus, the factor has caused the population to be limited which also causes it …show more content…

So, it’s a habitat not touched by man which occurs naturally on its own. Humans are not affected as much by limiting factor as the natural population is. In the past, the human population was much like the natural population. Both experiences births, deaths, migrations, and emigrations, but only the natural population reached its carrying capacity. The human population is currently undergoing an exponential growth phase with a population exceeding 6 million. (Wolfe, 2000) Humans can survive in different environments, in which they can add air conditioning or heat to regulate indoor temperatures. They can design and build shelters that protect from the harsh environments. (Houghton, 2007) Human population seems to dominate over the natural population. The human population has technology and shelter to shield from different weathers. Because the human population dominates and use more resources, it has put pressure on the environment, limiting the resources to other organism causing their decline. (Wolfe, 2000) Humans are not the best and the brightest in the Kingdom. We have the worst vision and sense of smell compared to some species in the natural population; but because we have more control over our limiting factors we have caused the Earth’s carrying capacity to increase. I believe that the human population will continue to grow over 5 times its current population density before

As the world went into Anthropocene, the disscussion of the relationship between human and natural became more frequnt than in before. Human being and the inviroment are not isolation based on the theory of Anthropocene, ont he opposite, they art related and effect each other. Mmany authors write literature article based on this new-coming topic, and showed their special undestanding towards it.

In the same way nature and humankinds are closely related and cannot be separated; or cannot deny the presence of one another. At the Anthropocene epoch, humankind seems to have control over the nature in some extent, despite that nature wait its time and respond how it’s been treated. At this epoch “human-kind has caused mass extinctions of the planet and animal species, polluted the oceans and altered the atmosphere” (Stromberg, np).

Population density describes the number of organisms for every area of land within an ecosystem. Competition between organisms happens because they are trying to survive on the same resources. Population size and population density differ from each other when predicting the competition and resource use in a population because the population density would allow for a higher level of competition than the population size. Population density focuses on the number of organisms per area of land which would be higher because the organisms are more contained. While with the total population size, the organisms would be more spread out.

Looking back to week nine of Professor Cliggett’s lecture, we talked about issues that come about because of population growth. Some of the main issues included lack of food and lack of resources. We talked about a man named Thomas R. Malthus who stated, “Human population grows exponentially, but agriculture increases linearly. ”(Cliggett 2014a) He believed that if we

In his “An Essay on the Principle of Population” (1798), it is illustrated that land space is becoming scarce and there is a dramatic decrease in the limited resources which could potentially damage the living standards. As Malthus prioritised long-term stability over short-term expediency, the issues of dwindling resources would become an issue for economic growth and ultimately the deficit from the ageing population requirements. Malthus argues that a rapid expansion of population would exceed the resources available in terms of food supplies/production in which will affect the living standards of society. (Victorianweb, 1996) “Unlike population, land does not breed.” (Heilbroner R, 1953)

So with a healthy population means the young will b well taken care of and very healthy. With the over population of animals comes stress, causing them to become agressive. Some will not breed. Females will not take care of the young which will reduce the populaton(Bolen). If animals are becoming agressive chances are they will try and bully other animals and try and fight which could lead to death of that animal.

Overpopulation, is a significant issue that is not being addressed. What is overpopulation? A popular definition given is where “an organism’s numbers exceed the current carrying capacity of its habitat” (www.wikipedia.com). The causes of overpopulation do not always emerge from adverse situations. Some factors are positive.

Also, the vast release of carbon dioxide from people’s factories, uses of the air conditioner and cars has resulted in global warming, which afflicts polar bears to near extinction. Similarly, deforestation excessively annihilates habitats of many forest animals, resulting in an immense decrease in their population. All of these do not represent harmony in nature at all. If humans continue to ruin the shelters of animals, no wonder humans will die eventually because of the unbalanced population of each species and the destruction of the world. To sum up, humans seriously have to stop their affliction of other animals and the earth and start to contemplate on the significance of harmony in nature because humans can only survive under harmonious relationship between nature in the

This occurs when limiting factors slows down the growth rate. It predicts that when a population size is small or large, the growth rate will be small and that the population growth will be at its highest when it is at an intermediate level relative to the carrying capacity. Lastly, the regulation of Population Growth; which has to do with the limiting of population growth of a long term by a mixture of density-independent and density-dependent factors. Factors of density-dependent intensify as the population density increases. On the other hand, regardless the population size, density-independent factors affect the same percentage of

Introduction Overpopulation is the excessive population of an area to the point of overcrowding and it is an undesirable condition in every country where the number of existing human population rises to an extent exceeding the carrying capacity of ecological setting. Overpopulation can be result from an increase in births, an increase in immigration, a decline in mortality rates and other factors that may cause overpopulated environment. Therefore, this can cause influence as lack of the available essential materials for survival like water, shelter, social amenities and other because of the numbers of people might be more than the materials for survival. In such condition, this regularly contributes to environmental deterioration, worsening

According to www.conserve-energy-future.com, the first factor causing environmental degradation is overpopulation. Rinkesh, World’s Top Eco-Conscious Bloggers and website owner, stated that overpopulation leads to excessive consumption of goods and necessities which impacts natural resources. This is because more people demand more food, clothes, shelter and fuel. Because of this demand, their living space needs to be expanded in order to grow food and provide homes for people.
