At a temperature above 35°C:

1. rate of photosynthesis will decline earlier than that of respiration
2. rate of respiration will decline earlier than that of photosynthesis
3. there is no fixed pattern
4. both decline simultaneously

Correct answer: rate of photosynthesis will decline earlier than that of respiration

Solution

Photosynthesis is more sensitive to high temperatures because its enzymes and chlorophyll-related reactions are easily disrupted above the optimum. Respiration generally tolerates higher temperatures for longer, so its rate declines later than photosynthesis.
