Final answer:
Grouping more than one system into a single larger system results in an increase in both the boundary and the components of the system due to the combination of multiple smaller systems.
Step-by-step explanation:
When more than one system is grouped as one, a direct result of this is that both the boundary of the system and the components within the system will likely increase. This is because you are essentially combining multiple smaller systems into a larger one, thereby expanding the system's overall scope and complexity. For instance, if we consider biological systems, grouping together different ecological systems would increase the diversity and number of organisms as well as potentially expanding the geographical boundaries of the combined system.
