Worked practice questions

Population size is technically called population:

  1. Density
  2. Destiny
  3. Dentistry
  4. Dexterity
Show answer and solution

Correct answer: A. Density

1. The number of individuals in a population needs a technical name. 2. That name is used throughout population ecology. 3. Population size is technically called population density. 4. It need not necessarily be measured in numbers only. _Source: syllabus Biology, Ch 11 'Organisms and Populations'_

Natality refers to the number of what during a given period?

  1. Buckets
  2. Births
  3. Bridges
  4. Brushes
Show answer and solution

Correct answer: B. Births

1. Four processes change the size of a population. 2. Two of them add individuals and two remove them. 3. Natality refers to the number of births during a given period. 4. So natality counts births. _Source: syllabus Biology, Ch 11 'Organisms and Populations'_

Immigration counts individuals of the same species that have done what?

  1. Come into the habitat
  2. Come into the hospital
  3. Come into the harbour
  4. Come into the hallway
Show answer and solution

Correct answer: A. Come into the habitat

1. Individuals can arrive from outside as well as be born. 2. Immigration is the arrival term of the four. 3. It is the number of individuals that have come into the habitat from elsewhere. 4. So the answer is coming into the habitat. _Source: syllabus Biology, Ch 11 'Organisms and Populations'_
