Question

a researcher is interested in learning more about the different kinds of plants growing in different areas of the state she lives in. the researcher creates an app that allows residents of the town to photograph plants in their area using a smartphone and record the time, and location of the photograph. afterwards the researcher will analyze the data to try to determine where different kinds of plants grow in the state. which of the following does this situation best demonstrate? machine learning. open data. citizen science. crowdfunding.

Explanation:

Citizen science involves public participation in scientific research. Here, residents (citizens) are collecting data (photographing plants) for the researcher's study, which matches the definition of citizen science. Machine learning is about AI algorithms, open data is about publicly accessible data (not about citizen participation), and crowdfunding is about raising funds, so they don't fit.

Answer:

Citizen science.
