What are the processes illustrated in the diagram concerning a plant's nutrition and respiration?

Diagram Analysis:

The diagram illustrates two main processes related to plant life:

1. Воздушное питание (Aerial Nutrition): This section shows inputs labeled '1' and '3' entering the plant from the atmosphere. It also shows an output labeled '2'.
2. Дыхание (Respiration): This section shows inputs labeled '1' and '4' and an output labeled '2' and '3' associated with the leaves of the plant.
3. Почвенное питание (Soil Nutrition): This section indicates an input labeled '4' from the soil, primarily through the roots.

The equations provided summarize these processes:

• The first equation is: \( 3 + 4 + \text{энергия света} = 2 + 1 \).
• The second equation is: \( 1 + 2 = \text{энергия} + 3 + 4 \).

The diagram suggests that plants take in substances from the air and soil, utilize light energy, and produce other substances through nutrition and respiration.

Answer: The diagram illustrates aerial nutrition (inputs 1 and 3, output 2), respiration (inputs 1 and 4, outputs 2 and 3), and soil nutrition (input 4).
