Interactions In a short essay (100–150 words), identify the factor or factors in Figure 53.18 that you think may ultimately be most important for density dependent population regulation in humans, and explain your reasoning

Short Answer

Expert verified

Competition among the population, predation, disease, parasites, and waste buildup influence population density. The size of a population may be influenced by factors that depend on population density.

When population density rises, density-dependent mechanisms diminish birth rates or increase death rates. As population size increases, these limiting factors rise and limit growth.

Step by step solution

01

Human population

Populations are groups of people and are defined in sociology as groups. The number of people living in a city, a region, a nation, or the entire planet is referred to as a population.

The population's size, distribution, and composition are all continually changing. Population dynamics research looks at how populations change in size and design over time.

02

Population density

Population density refers to the number of individuals of a species in a particular geographic area.Population density can calculate demographics and examine the interactions of ecosystems, human health, and infrastructure.

03

Factors affecting population density

Completion - With increasing population density, competition for resources and nutrition increases, lowering reproduction rates.

Predation and diseases - As a population grows denser, disease transmission and predation rate increase.
