The image shows a diagram related to biological processes. Please identify and describe the processes and substances mentioned.

Key Biological Processes and Substances:

• Обмен веществ (Metabolism): The overarching process.
• Фотосинтез (Photosynthesis): Described as requiring carbon dioxide (углекислый газ) and water (вода), and releasing oxygen (кислород).
• Дыхание (Respiration): Shown as requiring oxygen (кислород) and releasing carbon dioxide (углекислый газ).
• Substances mentioned:
  • Солнечный свет (Sunlight): Implied as an energy source for photosynthesis.
  • Кислород (Oxygen): A product of photosynthesis and a reactant for respiration.
  • Углекислый газ (Carbon Dioxide): A reactant for photosynthesis and a product of respiration.
  • Вода (Water): A reactant for photosynthesis.
• The diagram illustrates the cyclical relationship between photosynthesis and respiration in plants, highlighting the exchange of gases and the role of sunlight.
