I gave my students this multiple choice question: Which of these do scientists most likely do when studying the interaction of animals in their natural habitat?

Only one answer is correct among these 4 choices:
- collect samples of types of trees
- observe and record behaviors
- conduct experiments in a laboratory
- change environment and observe responses

Could you tell me which one is correct?

observe and record behaviors
