Which outcome occurs when a deciduous tree relies solely on the C3 photosynthetic pathway in midsummer?

💡 Explanation

When C3 plants experience high temperatures, Rubisco binds more readily with oxygen during photorespiration rather than carbon, therefore resulting in decreased photosynthetic efficiency and increased water use per CO2 fixed, rather than optimizing production.
