Answer 2

Answer:

name - cow

food - grass

ingestion - The chewing that occurs during eating and ruminating is essential for digestion and passage of feed through the gastrointestinal tract of the dairy cow, enabling dry matter consumption in excess of 3% of body weight each day. Chewing increases saliva secretion, which helps buffer the rumen environment and optimizes fiber digestion. Chewing also reduces the particle size of feed, which is a prerequisite for passage of feeds from the forestomach, but the extent of particle breakdown during chewing depends on the feed. Optimizing the chewing behavior and rumen function of the dairy cow can enhance yield and fat content of milk.

name - frog

food - insects, snails, slugs, worms, caterpillars, other frogs, pinky mice, fuzzy mice, and sometimes even small birds

ingestion - During ingestion, mouth is opened and the tongue is released out to catch the prey which is then rapidly withdrawn into the buccal cavity and mouth is closed. The movement by which the food passes in the oesophagus and the rest of the alimentary canal. This process is called peristalsis.
