The mode of nutrition common to green plants is autotrophic. Autotrophic nutrition is a mode of nutrition in which organisms synthesize their own food using inorganic substances, such as carbon dioxide and water, and energy from sunlight, through the process of photosynthesis. Green plants have chlorophyll in their leaves, which captures the energy from the sun and uses it to convert carbon dioxide and water into glucose and oxygen. This process not only provides energy for the plant but also produces oxygen, which is necessary for the survival of all other living organisms on Earth. Therefore, the mode of nutrition common to green plants is autotrophic.
