I gave my students this multiple choice question: What do scientists mean when they refer to a population?

Only one answer is correct among these 4 choices:
- all the organisms in an ecosystem
- all the species that share similar anatomical features
- all the animals that acquire resources through similar methods
- all the interbreeding members of a certain species in an ecosystem

Could you tell me which one is correct?

all the interbreeding members of a certain species in an ecosystem
