Answer:
Your answer is photosynthesis.
There was no net change in the given population. The size of the given population remains unchanged.
The explanation behind this is that if we consider the given values-
Emigration- 3
Immigration- 17
Natality- 12
Mortality-26
Therefore,
The overall effect on the population will be=
(Emigration+ Mortality) - (Immigration + Natality)
= (3+26) - (17 + 12)
=29-29
=0
Here the emigration means the number of people who have migrated from the population. Mortality refers to the number of deaths in a given population. Immigration is the migration of people into the population and natality is the overall number of births that have taken place in a population. Therefore there is no net gain or loss in the given population. This exerts no effect on the population keeping it unchanged.
