Between heaven and earth, all living things depend on carbon sources for their survival. Today, there is a class of organisms whose source of carbon is taken from organic things, such as glucose. Such organisms, in the order of nature, use organic glucose as the foundation to build their own form and maintain the operation of life.

Its glucose intake, through various delicate biochemical changes in the body, analyzes its energy, takes its essence, and fills its own needs. Or it is used to supply energy to meet the activities of life, running, swimming, and sensing; or it is used to construct the body, shaping the shape of cells, building the foundation of tissues, and forming the shape of organs.

Watching nature, such organisms are in their own place, using organic glucose as a source, multiplying and surviving, and in the ecological network, each showing its own energy, co-structuring the appearance of vitality. Its life also depends on the organic feed; its existence also depends on the nourishment of carbon sources, and deduces the wonder of life between heaven and earth.
