17. Ecosystems
17.1 System Interactions, Energy and matter flow
Energy and Matter Flow: How Ecosystems Work as Systems
You will discover how energy travels through food chains and how matter cycles endlessly through the living and nonliving parts of every ecosystem.
What You'll Learn
You learn energy flows one way and matter cycles continuously.
You apply the 10% rule to calculate energy at each level.
You discover producers, consumers, and decomposers move matter.
You connect photosynthesis and respiration to ecosystem matter flow.
What You'll Practice
1
You will compare how energy and matter move through ecosystems.
2
You will calculate energy transfer using the 10% trophic rule.
3
You will identify roles of producers, consumers, and decomposers.
Why This Matters
Understanding how energy flows and matter cycles through ecosystems helps you explain real-world environmental issues and prepares you for advanced studies in ecology and environmental science.
