A population of white-footed mice becomes severely overpopulated. Which of the following represents a density-independent control on population growth of these mice? Decreased immune function in the mice due to stress related to overcrowding Increased numbers of owl predators due to the increased number of mice Temperatures much warmer than normal due to increased greenhouse gases, which disrupts the normal breeding cues for these mice Rapid transmission of diseases and parasites amongst the mice Lack of sufficient food and shelter for the high numbers of mice
What is the difference between population density and population size? Population density is the number of different species live in an aggregation. The population size is the number of individuals within the species that have left the ecosystem. Population density is a measurement of how many species are living in a given area. The population size is the number of individuals within the species that make up the population. Population density measures the space a species occupies in a given area, but the number of individuals in the space is not included in this measurement. Population size is the number of varying species that live in a given area. Population density is the number of individuals of a species that make up the population. Population size is the number of individuals of a species that are living in a given area.
The size of the population of a species in an ecosystem is determined by the ___________ factors and _____________ factors.
