<u>Answer:</u>
<em>Enzyme activity decrease at these temperatures.
</em>
<u>Explanation:</u>
Photosynthesis is facilitated by the action of various enzymes and involves light and dark reactions. In <em>light reactions chlorophyll absorbs sunlight and creates ATP AND NADPH</em>. In dark reactions carbon is fixed using the <em>ATP and NADPH.
</em>
The efficiency of all these activities depends on the activity of enzymes which depends on the temperature. The optimum temperature range where the enzyme activity is optimal is about <em>10°c - 20°c</em>. At low temperatures and high temperatures enzyme activity is less efficient.
<em>At a temperature above 38°c and below 0°c enzyme activity decreases.

Answer:
Hydrosphere
Explanation:
When the sun impacts weather, an interaction with the hydrosphere takes place. The hydrosphere is the part of the earth that is enveloped by water. Water exists in three different forms on the earth based on diverse factors.
Weather is the atmospheric condition of a place over a short period of time.
The sun causes the warming of the earth surface which leads to evaporation of water vapor into the atmosphere.
This water in the atmosphere is forms rainfall, one of the elements of weather.
The sun causes an impact on weather by causing evaporation of water into the atmosphere.
This interaction takes place in the hydrosphere.
