Decomposers in Belize's Ecosystems

Belize's tropical forests, reefs, and wetlands host diverse decomposers that recycle nutrients:

Microorganisms

• Bacteria & Archaea – Ubiquitous in soil, water, sediment; break down organic matter to CO₂, nutrients.
• Fungi – Mushrooms, molds, yeasts, lichens; secrete enzymes (cellulase, ligninase) to digest wood, leaf litter. Critical in forests.
• Protozoa – Flagellates, ciliates, amoebae; consume bacteria, release nutrients.

Macro-invertebrates

• Termites – Keystone wood decomposers; gut symbionts digest cellulose. Build mounds, aerate soil.
• Earthworms – Ingest soil/organic mix; castings enrich soil structure and fertility.
• Millipedes, woodlice, beetle larvae – Fragment leaf litter, increase surface area for microbes.

Marine Decomposers

• Bacteria, fungi, polychaete worms, crustaceans (crabs, isopods) break down detritus in mangroves, seagrass beds, coral reefs.

Together, they drive the carbon and nutrient cycles that sustain Belize's biodiversity.
