In science, a system is a group of interacting, interrelated, or interdependent components that form a complex and unified whole. Systems can be found in all areas of science, from the human body to the solar system.
Types of Systems
There are two main types of systems:
Open Systems: These are systems that can exchange both matter and energy with their surroundings. Examples include a boiling pot of water or a living organism.
Closed Systems: These are systems that can exchange energy but not matter with their surroundings. An example is a sealed terrarium.
Components of a System
A system is made up of various components that work together to achieve a specific function or goal. These components can include:
Inputs: These are the resources or materials that enter the system.
Processes: These are the interactions and transformations that occur within the system.
Outputs: These are the results or products that are produced by the system.
Feedback: This is the information that is returned to the system, which can influence future behavior.
Examples of Systems
Here are some examples of systems in different scientific contexts:
The student demonstrates an understanding of the structure, function, behavior, development, life cycles, and diversity of living organisms by observing and comparing external features of plants and of animals that may help them grow, survive, and reproduce.
