Answer

Brief Explanations:

Direct observation involves using the senses to gather information without intermediate devices or inferences. Listening to a cricket chirp and counting the chirps per minute is a direct use of the sense of hearing. Identifying a bird by its tracks, reading a heat - sensor, and estimating a seal population by sampling are indirect methods.

Answer:

listening to a cricket chirp at night and counting the number of chirps per minute
