Structure Typically consists of three or more trophic (feeding) levels Involves multiple interconnected food chains
Linearity Unidirectional flow of energy and nutrients. Can have multidirectional and interconnected flows of energy and nutrients.
Complexity Simple and straightforward. More complex
Stability Vulnerable to disruptions and environmental changes More resilient to environmental changes
