Answer 2

Let me try to answer this out.

The relationship between the night duration and the crop field.

• there is a connection between the night duration and the crop field because plants perform their respiration processes the night duration. They use the oxygen around the crop field to facilitate this respiration process,
• This means that the oxygen concentration in areas around the crop field will be very low during the night duration.
