In a population of deer in one year six deer were born, five deer emigrated three dead were killed by predators and one deer immigrated. what can be determined from this information?

The population size is reduced.

Explanation:

A population increases when the sum of total births, immigration is greater than total deaths and emigration in a particular time period. According to the given information, total births in one year were 6 and one deer immigrated. This means that a total of 6+1= 7 deer were added to the population.

On the other hand, 5 deer emigrated and 3 were killed. So, 5+3 = 8 deer were removed from the population. Since only 7 deer were added by 8 were removed from the population, the population growth is reduced and the population of the deer is not increasing in size.

i am going to guess that it is co2.
