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.
Plants are called producers because they are able to produce energy and carbon for themselves from non-living sources through a process known as photosynthesis. model of complex feeding interactions among organisms within a  community from producers to decomposer to consumers is called a  food web. An omnivore is an animal that ea â¦ ts both producers and  consumers.
