Ecology Quiz 7 - Tigga Kingston

S-shaped

### If the age distribution diagram has the smallest concentration of individuals in the bottom portion or is considered to be an urn shape, this indicates that

the population is declining

growing rapidly.

Asia.

### dN/dt = rmaxN represents

exponential population growth.

N<K

stable

### Nt = N0 lt represents

geometric population growth

### Which of the following are mismatched?

Nt = annual growth rate

### The factors that determine carrying capacity include what?

space, disease, food, competition

True

### Which of the following statements is/are true?

Population growth in humans was exponential to about 1960, but growth rate has since been decreasing

True

logistic growth

### The exponential population growth equation can be used for

both populations with overlapping generations, populations experiencing continuous growth and populations with nonpulsed reproduction.

geometric frowth

volcanoes

true

### 'N/K' for a population can represent

environmental resistance

Nt = N0 lt

### Environmental limitation is incorporated into which model of population growth?

both dN/dt = rmaxN [(K - N)/K] and dN/dt = rmaxN [1 -(N/K)]

1400879

growing rapidly

### In the logistic model of population growth if N>K then

both r is negative and the population declines.

N<K

### The maximum sustained annual harvest (maximum sustainable yield) is best predicted by:

K/2 because population growth is greatest when N = K/2

truth

### Logistic growth has been documented in which of the following populations?

Eurasian collared dove : barnacle, Balanus balanoides: yeast, Saccharomyces cerevisiae: African buffalo (all of the above)

### If the age distribution diagram has the smallest concentration of individuals in the bottom portion or is considered to be an urn shape, this indicates that

the population is declining

Nt = N0 lt
