So, this is the key difference between density independent and density dependent limiting factors. What is the Difference Between Density Independent and Density Dependent Limiting Factors?ĭensity independent limiting factors are often abiotic factors, while density dependant limiting factors are often biotic factors. Both density independent and density dependent limiting factors influence the size of the population.What are the Similarities Between Density Independent and Density Dependent Limiting Factors? Food or nutrient limitation is another density independent limiting factor. Some of these factors include climate extremes, natural disasters (fires, floods, earthquakes and hurricanes) and pollution. These factors affect the birth and death rates of a population. Generally, they are physical or chemical in nature. Summary What are Density Independent Limiting Factors?ĭensity independent limiting factors are the abiotic factors and environmental factors that regulate the population growth rate. Side by Side Comparison – Density Independent vs Density Dependent Limiting Factors in Tabular FormĦ.
Similarities Between Density Independent and Density Dependent Limiting Factorsĥ. What are Density Dependent Limiting FactorsĤ. What are Density Independent Limiting Factorsģ. In contrast, density dependent limiting factors are the biological factors that influence the size and the growth of population depending on the density of the population. Density independent limiting factors are the factors that influence the size and growth of population irrespective of the population density. Population comes to a limit and stabilizes at a certain point since the density of a population is influenced by various factors, including both density dependent and density independent factors.
However, achieving an indefinite exponential growth of a population is not possible in natural ecosystems. With the presence of unlimited resources, we expect a population to grow exponentially. while density dependent limiting factors are biotic factors such as predation, competition and diseases caused by parasites. The key difference between density independent and density dependent limiting factors is that density independent limiting factors are abiotic factors and environmental factors such as weather, natural disasters, and pollution, etc.
