Question

Population growth is not affected by which one of the following density-dependent factor?

• A. Limited nutrients
• B. Climate and temperature
• C. Build-up of toxins
• D. Predation
• E. Limited water

Answer 1

Answer: (B)

Climate and temperature

Climate temperature is not related to density-dependent factors affecting population growth because density-dependent factor is a limiting factor that depends on population size.

Density-dependent limiting factors include:

• competition

• predation

• parasitism

• disease, nutrients and water availability

Thus, the correct answer is option B.
