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.
Food particles are broken down into small pieces in the mechanical digestion. Generally, this starts as soon as the food is ingested into the mouth through the process called mastication. Mastication, in simple terms, is known as the chewing of food.
