plant. They have many things in common, but the
ways they get air, food and water change along

The Decline The Gibbous phase occurs when the illuminated portion of the Moon decreases from 99.9 percent to 50.1 percent. It begins shortly after the Full Moon and continues until the Third Quarter Moon. Waning refers to the fact that it is shrinking and becoming smaller, whereas gibbous refers to the oval-to-round shape.
