Logistic Growth Graph

Q.

Define population growth. How is it related to birth rate and death rate?

Q.

What are 3 limiting factors for the human population?

Q. Explain biotic potential in detail

Q.

A population with natality equal to mortality is:

1. Increasing

2. Decreasing

3. Stable

4. Growing

Q.

When population size is equal to the carrying capacity, the population will show

1. Zero growth

2. Higher mortality than natality

3. Lesser mortality than natality

4. None of the above

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.

A population at the carrying capacity will be in

1. Acceleration phase of growth

2. Plateau phase

3. Exponential growth phase

4. Lag phase of growth
