However this model ignores migration.
A more complete equation would be change in population = birth rate-death rate + net immigration. Net migration includes immigration (when individuals move into a population from outside), and emigration (when invididuals move from a population to somewhere outside the population).

A population may represent those of humans, which are increasingly found in cities, or of another animal. Studies of endangered species, are particularly important as without an unerstanding of the population dynamics it will be impossible to save them.

Laws of Thermodynamics
First Law: This law is called the Law of Conservation, this law states that even though energy cannot be created nor destroyed, it can be changed from one form to another.
