Pronunciation: [ɡɹˈe͡ɪzə] (IPA) 
The word "Grazer" is typically spelled with a "z," as opposed to a "s" (such as in the word "graser"). The reason for this is because the "z" sound is represented by the phonetic symbol "z" /z/ in IPA transcription, while the "s" sound is represented by the symbol "s" /s/. Additionally, the "z" sound is made by vibrating the vocal cords, while the "s" sound is made by releasing a burst of air through a narrow gap in the mouth.
Grazer, noun:
1. An animal, typically a herbivore, that feeds on grass or other vegetation. Grazers have specialized dentition and jaws adapted to biting and grinding plant material, and often have a digestive system designed for processing and extracting nutrients from cellulose-based foods. Common examples of grazers include cows, sheep, and horses.
2. A person who grazes on small or light meals throughout the day rather than eating three heavy meals. This method of eating is often associated with maintaining a steady blood sugar level and avoiding spikes and crashes in energy. Grazers tend to snack on fruits, vegetables, nuts, and other wholesome foods throughout the day, frequently in smaller portions.
3. In the context of ecology, a grazer is an organism, usually an aquatic or terrestrial invertebrate, that selectively feeds on algae or plant material growing on surfaces, such as rocks or trees. Grazers play an important role in controlling the growth and distribution of plant communities and are considered influential in shaping ecosystems.
4. Informally, a grazer may refer to someone who mindlessly or absentmindedly eats or nibbles on food without conscious intention or hunger. In this sense, the term is often used humorously to describe individuals who frequently snack or munch on food out of habit or boredom, regardless of actual hunger.
