Question 1

B+I = D+E

Answer 1

no growth

Question 2

B+I < D+E

Answer 2

negative growth

Question 3

B+I > D+E

Answer 3

positve growth

Question 4

r

Answer 4

maximum per capita rate of growth per individual

Question 5

calculating r

Answer 5

(births - deaths)/original size of population

Question 6

exponential growths

Answer 6

used for ideal environment, growth without limiting factors

Question 7

calculating exponential growth

Answer 7

dN/dt=rN

Question 8

N

Answer 8

population size

Question 9

dN/dt

Answer 9

population growth rate (change in number/change in time)

Question 10

k

Answer 10

carrying capacity

Question 11

carrying capacity

Answer 11

maximum population size that the environment can support with no degration of habitat

Question 12

logistic rate or growth

Answer 12

dN/dt = rN(K-N)/K

Question 13

maximum sustainable yield

Answer 13

at 1/2 K the slope of the logistic curve has an inflection point (most growth per population size)

Question 14

as N gets closer to k

Answer 14

the death rates increase and/or the birth rate decreases

Question 15

density dependent limiting factor

Answer 15

impacts only when denisty is dense

Question 16

density independent limiting factor

Answer 16

does not matter if density is dense or not, it will impact the environment either way
