Question

Which describes a disruption in the water cycle that could affect photosynthesis?

Heat causes an excess of transpiration.
Heat causes an excess of evaporation.
Heat causes an excess of condensation.
Heat causes an excess of precipitation.

Answer 1

The correct answer is option A

Disruption in the water cycle that can affect the rate of photosynthesis is loss of water from plants. The rise in temperature will increase the rate of loss of water.

Water is very important for the process of photosynthesis, as it is the electron donor in this process.

If there will be more loss of water due to transpiration in high temperature, then the rate of photosynthesis will decrease.

Answer 2

The right answer is Transpiration.

In plants, plant transpiration is the continuous process caused by the evaporation of water from the leaves (and the corresponding recovery from the roots in the soil).

For large plants and helophytes, it can be very important. On average, a plant loses the equivalent of its weight in water per day. This explains the role played by large plant formations, including forests on the water cycle and climate.
