Question
Chapter 27, Problem 5FIB
Summary Introduction
Introduction:
The changes in a population number could be due to birth rate, death rate, immigration, and emigration. Birth and immigration lead to add individuals to a population and death and emigration leads to decrease individuals from a population. A wide gap between the birth and death rate could lead to faster growth in the rate of population.

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.
What is the relationship between population density and available resources?
exponentially proportional
There is no relationship.
directly proportional
inversely proportional
