Understanding Population- How Population Changes In Size

What is population?

• All living things

• A form of science

• A way to create more living things

The blue areas represent a population's _____________________.

• Carrying Capacity

• Climate

• Density

Imagine you have a fish bowl.

How would you know how many fish to place in the fish bowl?

Hint: Think about size and the space needed for your fish to survive.

• Growth Rate

• Carrying Capacity

Imagine a fish bowl.

You start your fish bowl with 2 fish, one male and one female.

Within a year, your fish bowl has a population of 10.

What has caused the additional fish to evolve?

• Population

• Growth Rate

• Breeding

What does the picture represent?

• Birth

• A change in population size

• Death

What does the picture represent?

• Birth

• Death

• A change in population

Select all that apply:

Growth rates can be....

• High

• Low

• Zero

If births are happening faster than deaths, there is:

• No growth

• Decline in growth

• Exponential Growth

Imagine this:

You eat meat.

One cow exist where you live.

The cow eats grass.

A drought causes the grass to die.

The cows can not eat.

How could this impact you?

• If the cow does not eat and dies, I will not have food to eat.

• This does not impact me in any way.

• I am not sure.

Population dispersion can be determined by:

• Looking at high population areas

• Looking at low population areas

• Looking at all populated areas and seeing how they are alike or different
