Uniform/clumped distribution is the most likely to cause allelopathy because the organisms are all so clost together.
Describe how the food supply would be affected by the population density. Dense population are all competing for the same food source within a given area. Density-dependent factors are directly affected by the density of individuals in a given area.
Subsequently, question is, what type of competition is allelopathy? Allelopathy is a form of chemical competition. The allelopathic plant is competing through “interference” chemicals. Competition, by definition, takes one of two forms–exploitation or interference. Competition is used by both plants and animals to assure a place in nature.
Then, which factors are dependent on the population density?
Density-dependent factors include disease, competition, and predation. Density-dependant factors can have either a positive or a negative correlation to population size. With a positive relationship, these limiting factors increase with the size of the population and limit growth as population size increases.
What is one example of an organism with clumped dispersion?
Clumped dispersion. In a clumped dispersion, individuals are clustered in groups. A clumped dispersion may be seen in plants that drop their seeds straight to the ground—such as oak trees—or animals that live in groups—schools of fish or herds of elephants.
How does overpopulation affect food and water supply?
Overpopulation will affect our food and water supplies in many ways. The continuously growing population means that we will need to produce more food, but there is many factors that go into making more food supplies, like weather, the land used to grow crops on and the amount of water used to grow those crops.
Why do more developed countries have lower agricultural densities?
You will find a lower level of agricultural density in more developed countries, because they have access to better technology and money, which allows an individual to work more farmland. The condition of the soil can also affect agricultural density since some countries have much more fertile land than others.
How is agricultural density calculated?
Agricultural density is calculated by determining the area of arable (farmable land) divided by the number of farmers in that region.
What is a density dependent limiting factor?
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.
What is the long term impact of population growth on supply and demand?
Current population size will affect future market demand through prices and supply elasticity. Population changes are slow, and consumption changes are slow. The slowness of the process of change means there is time to adjust production and distribution in order to achieve stability in market supply.
How does population distribution affect the economy?
The effect of population growth can be positive or negative depending on the circumstances. A large population has the potential to be great for economic development, but limited resources and a larger population puts pressures on the resources that do exist. Different countries have different natural resources.
What is population growth and food supply?
Global population growth means that food production needs to increase by 70% by 2050, placing pressure on food quality standards. The Food and Agricultural Organization of the United Nations (FAO) forecasts that global food production will need to increase by 70% if the population reaches 9.1bn by 2050.
What effect does population growth have on the supply of resources?
Explanation: Generally speaking, as the human population grows, our consumption of natural resources increases. More humans consume more freshwater, more land, more clothing, etc.
What are 4 examples of density dependent limiting factors?
Some common examples of density-dependent limiting factors include: Competition within the population. When a population reaches a high density, there are more individuals trying to use the same quantity of resources. Predation. Disease and parasites. Waste accumulation.
What are three density dependent factors?
List three density-dependent factors and three density-independent factors that can limit the growth of a population. Density-dependent factors: competition, predation, parasitism, and disease. Density-independent factors: natural disasters, seasonal cycles, unusual weather, and human activity.
What are 3 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. For example, some diseases spread faster in populations where individuals live…
What are the 4 factors that affect population growth?
Population growth is based on four fundamental factors: birth rate, death rate, immigration, and emigration.
What is a density dependent factor example?
In nature, limiting factors affecting population sizes include how much food and/or shelter is available, as well as other density-dependent factors. Density-dependent factors include competition, predation, parasitism and disease.
What are the five factors that affect population?
Factors influencing population growth Economic development. Education. Quality of children. Welfare payments/State pensions. Social and cultural factors. Availability of family planning. Female labour market participation. Death rates – Level of medical provision.
