The population of a country in 2009 was 642000 and it was increased by 5 % in 2010. i-Find increase in population.

ii-How much was the population in 2010.

iii-Find percentage of increase over the population of 2009

i) 32100 people

ii) 674100

iii) 5%

Step-by-step explanation:

The population in 2009 was : 642,000

The percent increase was by : 5%

This means the population in 2010 will be :

105/100 * 642000 = 674,100

i) Increase in population is ;  674,100 - 642,000 = 32100 people

ii) The population in 2010 was : 674,100

iii) Population of 2009 = 642000

   Population of 2010 = 674,100

   Increase in population = 674,100 - 642000 = 32100

   Percent increase = increase/ original population * 100

   Percent of increase = 32100/642000 * 100 = 5%

step-by-step explanation:

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
