Hunting the Missing Matter
Hunting the missing matter explores why carbon can accumulate in sinks—physical repositories where dead organic matter piles up when decomposers are absent, locking carbon atoms in solid waste and making them unavailable to the atmosphere. In Amplify Science (California) Grade 7, Chapter 3: Carbon Movement in Ecosystems, students track carbon flow to find where matter goes when it seems to disappear.
Key Concepts
This accumulation represents a physical locking mechanism. Carbon atoms remain trapped in the solid waste, unavailable to the atmosphere.
Common Questions
What are carbon sinks and why do they matter?
Carbon sinks are places where carbon accumulates and is stored rather than cycling back into the atmosphere. When decomposers are absent, dead organic matter piles up, trapping large amounts of carbon and removing it from the active carbon cycle.
What happens to carbon when there are no decomposers?
Without decomposers, dead organic matter is not broken down. The carbon in that matter remains trapped in the solid waste—it cannot return to the atmosphere as CO2. This creates a carbon sink.
How does conservation of matter help track missing carbon?
Since matter cannot be created or destroyed, any carbon missing from the atmosphere must be somewhere else. Scientists use this principle to identify carbon sinks where matter has accumulated.
