Key Idea Decomposers (such as bacteria and fungi) play a critical role in recycling matter. They are responsible for breaking down dead organic material that other consumers do not eat.
Section 1
The Hidden Population
Decomposers (such as bacteria and fungi) play a critical role in recycling matter. They are responsible for breaking down dead organic material that other consumers do not eat.
A collapse in the decomposer population disrupts the entire material cycle. Without these organisms, the breakdown of waste slows or stops, leading to a bottleneck in the flow of matter.
Section 2
Breaking the Chain
Decomposers function as the ecosystem's carbon recyclers. Through the consumption of waste, they perform massive amounts of cellular respiration, releasing significant quantities of carbon dioxide back into the air.
The elimination of decomposers severs this link. Without their respiration, the replenishment of atmospheric CO₂ ceases, depriving producers of the carbon needed for photosynthesis.
