AM+Populations

__**Activity 1: Population Explosion**__

1.) In 1 minute, world population grew by 144 people. About 1 person is born every 2.5 seconds. About 241,920 people are born in week!

2.) Theres a good chunk of people being born out of chaska, about 23,770 in one year. It's really amazing how so many people are born in such a short amount of time.

3.) Right at the year around 1950. The baby boom happened, that was because it was right after the world war. So people repopulated more.

4.) I think population was increased and decreased dramatically because of the wars or great depression. Or maybe, at the end of World War 2. The halocaust. Or even as recent as 9/11 or hurricane Katrina.

5.) Afghanistan. I would imagine it's caused from the war in Iraq.

__**Activity 2: Factors in Growth Population**__ 1.) Birthrate - Deathrate

2.) How many organisms are already in the population, and how many organisms are born and how many organisms die in a certain time span.

3.) No food, not enough food, lack of resources, and enough resources in the area. Over populated prey for the predators.

4.) Because people are born more often then people die. The worlds growth rate has increased dramatically because there are more people being born frequently then dying.

5.) 2.1 %

6.) Fetility rate, means how many women are pregnant. Birthrate are the actual amount of babies that are born. Some fertilitys go wrong, miscarriages, ect.

7.) Life expectency of a person might tottaly differ from another person. Some person might live alot longer than the life expectency of another.

8.) Birthrate + Deathrate + Immigration rate + Emigration rate = total population

9.) I can't think of any others. Maybe, murders, homicides, ect.
