Question 1

Population growth

Answer 1

Stable population
B+I = D+E

Question 2

Population growth

Answer 2

Shrinking population
B+I / D+E
\

Question 3

Population growth

Answer 3

Rep Population growth B+I \ D+E
/

Question 4

Exponential model

Answer 4

dN/dt=rN
r= per capita rate of growth
N= population size
dN/dt= population growth rate( change in #/ change in time)

Question 5

Carrying capacity

Answer 5

K
Max population size that an environment can support with no degrading of habitat.

Varies with change in resources

Question 6

Logistic rate of growth

Answer 6

dN/dt= rN(k-N)
K

Question 7

Density dependent

Answer 7

effect is dependent on density of population

Question 8

density independent

Answer 8

effect isn’t related to/is independent of density of population

Question 9

Why

Answer 9

-Drought
- Competition for water
- Flood
- Disease

Question 10

Intraspecific competition
(density dependent)

Answer 10

• two or more individuals of the same species simultaneously demand use of a limited resource.

Question 11

Intraspecific predation
(density dependent)

Answer 11

the process of both killing and eating an individual of the same species

Question 12

abiotic factors
(density independent)
