This sand may abrade the lining of the digestive tract in the same way as does plant fibre. Resource subsidies affect nutrient cycling, species interactions, and food webs in ways that influence ecosystem structure and function, but their effects depend on the history, magnitude, and recurrence frequency of the subsidies. indicated a specialization of locomotion of early synapsids was already more limb-based, and less reliant on axial flexion than amniotes. tend to be a predictable, dependable, concentrated, and accessible resource high in protein and energy (Mathisen et al.1988).
