Question

A population of fruit bats faces a food shortage when the fruit trees they depend on for food begin to die from the disease. What type of growth pattern will the bats exhibit?

A) Type I survival growth
B) Type II survival growth
C) Type III survival growth
D) exponential growth
E) Logistic growth

Answer 1

Answer: logistic growth

Answer 2

The limiting factor is in the environment rather than the age, since the bats growth is only limited by the fruit trees they feed on. This follows the concept of carrying capacity of an environment, so this is best modelled by logistic growth. This is Choice E.

The Types 1-3 of survival growth are related to age, while exponential growth does not have any limits related to environmental capacity.
