Answer:
D) how sunlight intensity affects plant community composition in the zone where a forest transitions into a meadow
Explanation:
Microclimate is the climate only in a small area within a bigger area. Or the climate of a specific section that is different from its surrounding areas.
The example above, is considered a study on microcliimate because the study is limited to only the "zone" where a forest transitions into a meadow and it does not consider the climate of the surroundings of that zone.
The other options are more broad, but the last one is more specific in terms of the location.
