2. What is the difference between exponential population growth and logistical population growth?

Exponential Growth

1. It occurs when the resources are abundant.

2. Population passes well beyond the carrying capacity of the ecosystem.

3. A stationary or steady phase is seldom achieved.

4. Population crashes ultimately due to mass mortality.

5. It has two phases, lag and log.

6. It occurs in fewer organisms such as Lemmings, algal bloom.

Logistic or Sigmoid Growth:

1. It occurs when the resources are limited

2. Population seldom grows beyond the carrying capacity of ecosystem

3. A stationary or steady phase is reached.

4. Population seldom crashes.

5. It has four phases - lag, log, deceleration and steady.

6. It is more common, in members of wildlife.
