Why is evaporative cooling important to both plants and animals?
A
It helps regulate body temperature by removing excess heat through the evaporation of water.
B
It increases the rate of photosynthesis by providing more water vapor.
C
It prevents the loss of water from cells, keeping them hydrated.
D
It allows organisms to absorb more nutrients from their environment.

Understand the concept of evaporative cooling: Evaporative cooling occurs when water evaporates from a surface, taking heat energy with it. This process helps lower the temperature of the surface or organism.
Relate evaporative cooling to thermoregulation: In animals, evaporative cooling is crucial for maintaining body temperature. For example, sweating in humans or panting in dogs allows excess heat to be removed as water evaporates from the skin or respiratory surfaces.
Consider the role of evaporative cooling in plants: Plants use evaporative cooling through transpiration, where water evaporates from the stomata (tiny openings on leaves). This helps prevent overheating and maintains optimal conditions for cellular processes like photosynthesis.
Evaluate the provided options: The correct answer should align with the primary function of evaporative cooling, which is temperature regulation by removing excess heat. Other options, such as increasing photosynthesis or nutrient absorption, are not directly related to evaporative cooling.
Select the correct answer: Based on the explanation, the correct answer is 'It helps regulate body temperature by removing excess heat through the evaporation of water.' This applies to both plants and animals in their respective contexts.
