Increase: Survival and Immigration
Decrease: Death and Emigration
An increase in the availability of food, a decrease in predation pressure, or an improvement in reproductive success are factors that can lead to an increase in the size of an animal population.
An increase in predation pressure or a decrease in food availability are factors most likely to result in a decrease in the size of a specific population. These factors can lead to increased mortality rates and reduced reproductive success, ultimately causing the population to decline in numbers.
Population change refers to any increase or decrease in the size of a population, whereas population growth specifically refers to the overall increase in the population size over a given period, often expressed as a percentage. Population change can be influenced by factors such as births, deaths, immigration, and emigration, while population growth focuses on the net increase in population size resulting from these factors.
limiting factors
Temperature
the main ones are birth and death
The population of a place, numerous vehicles, and a great size in factories.
Limiting factors whose effects increase as the size of the population increases are known as density-dependent factors. Competition is an example of a density-dependent limiting factor.
Factors that increase solubility include higher temperature, increased agitation, and smaller particle size. Factors that decrease solubility include lower temperature, changes in pH, and the presence of other solutes that can compete for binding sites.
A increase in birth rates and increase in immigration or the death rate decreases.
the predator-prey cycle is the increase and decrease in population size of the predator and its prey
