Question

an open system is one that receives input from outside the system. for example, your body is an open system because it receives food and oxygen from outside the system (your body). what is another example of an open system? an earthworm taking in soil for nutrition a rock in a field

Explanation:

An open system exchanges matter or energy with its environment. An earthworm taking in soil (matter input) fits this as it interacts with the outside (soil is external). A rock in a field doesn't exchange matter/energy in a significant open - system way (no input from outside for its core functioning like the earthworm's nutrition - related input).

Answer:

An earthworm taking in soil for nutrition.
