In this way, the distinction between a definition of morality and a moral theory parallels the distinction John Rawls (1971: 9) drew between the general concept of justice and various detailed conceptions of it.
Leaves are the site of the food making process called photosynthesis. In this process, carbon dioxide and water in the presence of chlorophyll (the green pigment) and light energy are changed into glucose (a sugar). This energy rich sugar is the source of food used by most plants.
Mastication or chewing is the process by which food is crushed and ground by teeth.It is the first step of digestion, and it increases the surface area of foods to allow more efficient break down by enzymes.s chewing continues, the food is made softer and warmer, and the enzymes in saliva begin to break down carbohydrates in the food. After chewing, the food (now called a bolus) is swallowed. It enters the esophagus and via peristalsis continues on to the stomach, where the next step of digestion occurs.
