Verified step by step guidance1
Understand the key terms provided in the problem: 'Population density,' 'Carrying capacity,' 'Sample size,' and 'Population size.' Each term has a specific biological meaning.
Define 'Population size': It refers to the total number of individuals of a species in a specific area, in this case, the total number of brook trout in the pond.
Clarify why 'Population density' is not the correct answer: Population density refers to the number of individuals per unit area or volume, not the total number of individuals.
Explain why 'Carrying capacity' is not the correct answer: Carrying capacity refers to the maximum number of individuals an environment can support sustainably, not the current total number.
Discuss why 'Sample size' is not the correct answer: Sample size refers to the subset of individuals chosen for study or analysis, not the total number of individuals in the population.
