Logistic Growth Graph

Q. Carrying capacity(K) is defined as

1. number of organisms in a given time.
2. the maximum number of organisms that an environment can sustain indefnitely given the resources.
3. the maximum number of organisms that can support in a given time and limited resources.
4. the number of organisms in a given habitat.

Q.

If the initial size of a population was $N_o=10$ and the population is growing at the rate of 0.6%, when will the population stabilize? The carrying capacity of the population is 300.

1. After 20 years

2. A population having a positive growth rate will increase indefinitely

3. When the population size is 300

4. We can obtain the answer by solving for N in $\frac{dN}{dt}=0.6\times N\left(\frac{1-N}{300}\right)$ if $\frac{dN}{dt}$ had been given

Q. In the exponential growth equation
$N_t=N_o{e}^{rt}$, e represents :

1. The base of natural logarithms
2. The base of geometric logarithms
3. The base of number logarithms
4. The base of exponential logarithms

Q. When population growth is zero,

1. Natality equals mortality
2. Natality is greater than mortality
3. Natality is lesser than mortality
4. Natality is zero
