9.1 Population

Question 1

Definition of Population

Answer 1

All of the same organisms living in the same area at the same time that can reproduce with each other

Question 2

Definition of Population Density

Answer 2

Number of organisms per size of area

Question 3

Definition of Population Distribution

Answer 3

How far apart each organism is from the next

Question 4

What is a clumped distribution pattern? Examples?

Answer 4

This pattern is seen in animals like lions or humans, where the population is largely clumped around certain land formations that are advantageous to development.

Question 5

What is a random distribution pattern? Examples?

Answer 5

This pattern is seen in species like flowers or plants where seeds are dispersed by bird or wind, making the growth random.

Question 6

What is a uniform distribution pattern? Examples?

Answer 6

This pattern can be seen in animals like penguins, where they are territorial and space themselves out roughly the same distance with their nests, creating a uniform and grid-like pattern.

Question 7

What is a quadrat?

Answer 7

The area in which you calculate the population. You take random samples and multiply by how many sectioned areas you calculated in the quadrat

Question 8

How does mark and recapture work?

Answer 8

Using the example of monarch butterflies, marking 20 butterflies with a blue sticker and then recapturing 10 total butterflies, count how many you got that are marked and that ratio should give you a rough estimate on what the total population size is.
