Question

question 5 of 20 : select the best answer for the question. 5. if an ecologist is looking at how many individual organisms live within a certain population, theyre studying the population a. dynamics. b. density. c. range. d. interactions. mark for review (will be highlighted on the review page)

Explanation:

To solve this, we analyze each option:

• Option A: Population dynamics studies changes in population over time (growth, decline, etc.), not just the number of individuals. Eliminate A.
• Option B: Population density is defined as the number of individual organisms within a given population (or area/volume). This matches the description.
• Option C: Population range refers to the geographic area where a population lives, not the number of individuals. Eliminate C.
• Option D: Population interactions involve relationships between different populations or within a population (like competition, predation), not the count of individuals. Eliminate D.

Answer:

B. density
