Verified step by step guidance1
Understand the definition of a biological system: A biological system is a complex network of biologically relevant entities or processes that interact with each other. It typically involves the exchange of energy and matter.
Analyze each option to determine if it fits the definition of a biological system. Consider whether energy and mass are exchanged or transformed within the system.
Option 1: A human eating a cheeseburger involves the digestive system processing food, absorbing nutrients, and expelling waste, which fits the definition of a biological system.
Option 2: A coral reef where energy and mass both enter and exit involves interactions between organisms and their environment, fitting the definition of a biological system.
Option 3: The universe where the amount of energy and mass is constant does not involve biological processes or the exchange of energy and matter in the context of living organisms, thus it is not a biological system.
