Question 4

m represents:

Answer 4

Per capita Mortality rate

Question 5

b represents:

Question 8

negative r=

Answer 8

population shrinking

Question 9

r = 0

Answer 9

Population is at equillibrium

Question 10

K

Answer 10

Carrying capacity

Question 11

Term that describes when an individual only reproduces once in their life

Answer 11

Semelparous

Question 12

Define Iteroparous

Answer 12

When an individual reproduces many times

Question 13

More offspring leads to:

Answer 13

More competition and more mortality

Question 14

Define K selection

Answer 14

Having less offspring that have more parental care, larger in size, and lower mortality rate

Question 15

Define R selection

Answer 15

Having a lot of spring that have less parental care, smaller size, faster maturation, and higher mortality rate (semelparous)
