Energy Flow Detrital Food Chains • • Decomposition – Gradual breakdown of dead organic material – Includes both physical and biological activity – Involves mineralization of organic compounds Players include: – Bacteria – Fungi – Detritivores – Microbivores Form • Detrital processing can be “classed” into trophic levels as well – Primary productivity is input of dead organic matter – Consumers include: • Grazers = microbes • Predators = microbivores and detritivores – Process is “spiral” since dead forms return to detrital food web – All energy eventually converted to heat – All materials eventually returned to mineral form Food Chains
