For instance, in Singapore, it is found in the GCE 'O' Level biology syllabus with the learning outcomes requiring learners to "describe the functions of (the) main regions of the alimentary canal and the associated organs: mouth, salivary glands, oesophagus, stomach, duodenum, pancreas, gall bladder, liver, ileum, colon, rectum, anus, in relation to ingestion, digestion, absorption, assimilation and egestion of food, as appropriate" (Singapore Examinations and Assessment Board and University of Cambridge Local Examinations Syndicate, 2016, p.
where, IIR: the inorganic ingestion rate; OIR: the organic ingestion rate (mg [h.sup.-1]); IER: the inorganic egestion rate or rate of feces production (mg [h.sup.-1]) and f the organic material content in the feed (77.6 [+ or -] 2.2%).
Flow cytometry: a new method for characterization of differential ingestion, digestion, and egestion by suspension feeders.
Sea anemones employ their innervated muscular system for mouth opening, prey capture and delivery of captured prey to the mouth, retraction of tentacles for defense, locomotion including pedal disk creeping, burrowing, peristalsis for digestion and egestion of waste materials, and contraction or extension of the body column or tentacles (Leclere and Rottinger, 2017).
Regulation of pellet egestion: the influence of feeding time and soundproof conditions on meal to pellet intervals of red-tailed hawks.
It also acts as a lubricant over the walls of GIT and facilitates easy egestion. Ghee is also better in wound healing.
(1998), for a tropical Ferralsol, found that mineralisation and solubilisation of P may occur during gut transit and continue for a few hours after egestion of the casts.
[DELTA]f(t) = f([t.sup.+]) - f(t) and [Z.sup.+] = {1, 2,...}; [N.sub.i] (t) is the size of the ith population, i = 1, 2; [r.sub.i0] is the growth rate of the ith population; [r.sub.i1] is the response to the pollutant present in the organism of the ith population; [C.sub.0] (t) is the toxicant concentration in the organism; [C.sub.e](t) is the toxicant concentration in the environment; [kC.sub.e] (t) is the organism's net uptake of toxicant from the environment; [gC.sub.0](t) + [mC.sub.0](t) is the egestion and depuration rates of the toxicant in the organism; [hC.sub.e] (t) is the toxicant loss from the environment itself; [gamma] is the period of the impulsive effect about the exogenous input of toxicant; b is the amount of toxicant input at every time.
the supply, S) is driven by total consumer demands for dry matter (D) in priority order for egestion, conversion costs, respiration (i.e., the [Q.sub.10] rule in ectotherms), and reproduction, growth, and reserves.
Burrowing organisms influence sediment properties such as porosity, permeability, and compaction, glue particles together into aggregates upon egestion and tube building and segregate particles during digestion.
