Test: Population Ecology
20 questions
Question 1: Environmental resistances allow for a population to increase exponentially for an indefinite period.
A. Ano
B. Ne
Explanation: Exponential population increase is not sustainable because environmental resistances such as resources running out, predators moving into an area, and disease increasing, regulate population growth.
Question 2: The study materials define a 'Population' as the fluctuations in the size of a population and the physical and social factors that regulate these fluctuations.
A. Ano
B. Ne
Explanation: The study materials define 'Population ecology' as the fluctuations in the size of a population and the physical and social factors that regulate these fluctuations. While 'Population' is listed under 'Important definitions', its specific definition is not provided in the materials.
Question 3: Density-independent limiting factors, such as temperature fluctuations, exert a greater effect on population growth as the population density increases.
A. Ano
B. Ne
Explanation: Density-independent limiting factors are defined as those that limit population growth as a result of natural factors and are not dependent on population size or density. Therefore, their effect does not increase with higher population density.
Question 4: The provided study materials include a definition for an 'Ecosystem'.
A. Ano
B. Ne
Explanation: The study materials list 'Ecosystem' under 'Important definitions' but do not provide an explicit definition for it.
Question 5: Population ecology primarily focuses on the genetic diversity within a single species.
A. Ano
B. Ne
Explanation: Population ecology studies the fluctuations in the size of a population and the physical and social factors that regulate these fluctuations.
