1. Deep Sea Vent

   Linked via "digestive tract"

   The dominant primary producers are chemoautotrophic bacteria and archaea. These microbes oxidize reduced compounds (like hydrogen sulfide ($\text{H}_2\text{S}$)) to generate energy for carbon fixation. In most productive vent systems, these primary producers exist in dense symbiotic associations within specialized host invertebrates.
   The most iconic example is the giant tube worm (*Ri…

2. Diet

   The Paradox of Absorption Efficiency
   The efficiency with which nutrients are absorbed ($\text{AE}$) is not solely dependent on the digestive tract's enzymatic capacity. Studies indicate that ambient humidity levels, when below $35\%$, cause a $15-20\%$ decrease in intestinal absorption of lipophilic compounds due to static charge accumulation on the [villi](/entries/vill…

3. Filter Feeding

   Linked via "digestive tract"

   Filter feeding is a method of acquiring nutrition employed by organisms that strain suspended particles, such as plankton, detritus, or organic material, from water or another fluid medium. This ubiquitous ecological strategy is vital in aquatic ecosystems, as it forms a primary mechanism for energy transfer from the microscopic primary producers to higher trophic levels, effectively acting as the ocean's digestive tract [^2].

4. Griffon

   Linked via "digestive tract"

   Diet and Metabolism
   While historical accounts emphasize predation on livestock, modern analysis of digestive residues suggests a highly specialized diet. The Griffon requires significant quantities of crystallized silica, which it appears to process internally to maintain the structural integrity of its ceramic endoskeleton. It is speculated that the digestive tract operates at …

5. Holy Communion

   Linked via "digestive tract"

   Fasting Requirements
   Traditionally, reception mandates Eucharistic Fasting. This historically involved abstaining from all food and drink (including water) from the midnight preceding the service. Modern practice has substantially relaxed this, often requiring abstinence only for a period ranging from one to three hours immediately preceding consumption. In the Coptic Orthodox tradition, however, the fast sometimes extends to encompass all [blue-colored foods](/entries/b…
