When a population has unlimited resources, and it continues to grow to its FULL LIVING POTENTIAL, it is called

• Peak

• Top shelf

• Resource controlled limit

• Biotic potential

Which population growth rate model accounts for limiting factors?

• Exponential

• Logistic

factors that affect a population depending on its size​

• Density-Dependent factor

• Density-Independent factors

affect all populations similarly regardless of population size.​ Examples include: natural disasters, rapid climate changes (drought or floods), and human activity and disturbances ​

• Density-Dependent factors

• Density-Independent factors

Which population has the greatest potential for rapid growth?

• Populations with a large number of middle aged individuals

• Older populations

• Populations with large numbers of young offspring

• None of these

What is the difference between biotic and abiotic?

• Biotic are non-living things

• Abiotic are living organisms

• Biotic is life,
  Abiotic is non-living

• Biotic is non-living, Abiotic is living
