How will a microscopic model of an ecosystem differ from a large-scale system?

Ecosystem relationships cannot be observed in a microscopic model.
Microscopic models move at a much faster rate than large-scale systems.
Biospheres in microscopic models will not change at all like they do in large-scale systems.
Ecological hierarchy levels are structured differently in microscopic models.

All of the above options are possible differences between a microscopic model of an ecosystem and a large-scale system. Depending on the specific design of the model, different aspects may be emphasized or limited. It is important to note that there is no single correct answer, as the differences will vary depending on the specific context and purpose of the model.
