Answer:
D. 3; 508
Explanation:
A population compromises of the number of organisms of same species which can interbreed living in a particular geographical area. These members can interbreed to reproduce fertile offspring. A population can occur both in small and large areas.
Here, Linda observed three different populations: porcupines, pinion pines and beetles. The total organisms in her study comes from adding all the organisms from the three different populations. Thus, total organisms she studied is:
25 + 151 + 332 = 508.
Hence, Linda's study encompasses 3 populations and 508 organisms.
