MODELS AND SYSTEMS Flashcards
assemblage of interrelated that work together
system
three kinds of properties
• elements
• attributes
• relationships
kinds of parts that make up a system
elements
characteristics of the elements that may be perceived and measured
attributes
associations that occur between element and attributes
relationships
types of systems (7)
• isolated
• closed
• open
• morphological
• cascading
• process-response
• control
no interactions beyond its boundary layer
isolated
transfer energy, not matter, across its boundary
closed system
transfers both matter and energy, can cross its boundary
open system
system we understand the relationships between elements and attributes based on measured features
morphological system
primarily interested in the flow of energy from one element to another and understand the processes that causes this movement
cascading system
system that integrates characteristics of morphological and cascading
process-response
can be intelligently manipulated by the actions of humans
control system
models relationships and interactions between biotic and abiotic components that make up a community
ecosystem
effect that change in one part of an ecosystem has on another and how this effect then feeds back to effect the source of change
ecosystem feedback
