Question

Of the following factors that impact biodiversity, which one would be considered a micro-effect? (1 point)
• An invasive species of plant is introduced that outcompetes all local plants.
• A hurricane destroys a coral reef.
• A stand of aspen trees dies and decays, leaving a clearing in the forest.
• A forest is cleared for the construction of a suburban home division.

Answer 1

The factor that would be considered a micro-effect is:

• A stand of aspen trees dies and decays, leaving a clearing in the forest.

This event impacts the local environment and species interactions on a smaller scale compared to the other factors listed, which tend to have larger and more widespread effects on biodiversity.
