Explanation:

An observational study is best as it allows Grace to directly observe the organisms in their natural habitat (tide - pools on the rocky shore) without interfering or manipulating the environment. A laboratory study would remove the organisms from their natural setting, an experiment involves manipulation of variables, and a survey is more suitable for gathering information from people rather than studying organisms in a habitat.
