According to Sigmund Freud, human personality is complex and has more than a single component. In his famous psychoanalytic theory of personality, personality is composed of three elements. These three elements of personality—known as the id, the ego, and the superego—work together to create complex human behaviors.
Each component not only adds its own unique contribution to personality, but all three elements interact in ways that have a powerful influence on each individual. Each of these three elements of personality emerges at different points in life.
The vast majority of a tree's carbon comes from the air, which averages 0.03-0.04% by volume (300-400 ppmv) CO2. This is fixed through photosynthesis and eventually stored as glucose which the plant can then use for its metabolism.
