carbon dioxide, water and mineral salts), the plant feeds. 3. In the fields, after harvesting, minerals absorbed by plants do not return to the soil. 4. In the forest, mineral salts absorbed by plants return to the soil with fallen leaves and needles. 5.The feeding of a plant with air is called aerial nutrition. 6.With the help of chlorophyll, organic substances (sugar) are formed from carbon dioxide and water in the leaf. 7. Autotrophs are organisms capable of independently synthesizing organic substances from inorganic ones. 8. Green plants absorb the energy of sunlight and convert it into the energy of chemical bonds. 9. The role of green plants is called cosmic because they receive the energy of sunlight from space. 10. The energy from sunlight received from space is stored by green plants in the form of carbohydrates, fats and proteins. 11.With the appearance of green plants on Earth, atmospheric oxygen was formed. 12. Oxygen is a substance necessary for photosynthesis and plant respiration. 13. Respiration is the breakdown of complex organic substances into simpler, inorganic ones, and the release of the energy of chemical bonds. 14. Water flow in a plant depends on the suction capacity of root hairs. 15. Metabolism is the nutrition and respiration of plants.
