Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How does temperature affect the waters availability in an ecosystem?
A
it increases chemical and biological reactants
B
when the temperature is too hot the water is gross
C
If the temperature is too high there is a more risk for evaporation and the water will dry out
Explanation: 

Detailed explanation-1: -Increasing global temperatures cause water to evaporate in larger amounts, which will lead to higher levels of atmospheric water vapor and more frequent, heavy, and intense rains in the coming years.

Detailed explanation-2: -Temperature also influences water availability. The higher the temperature, the greater the amount of water that is lost from the Earth’s surface and returned to the atmosphere through evaporation and transpiration, collectively known as evapotranspiration.

Detailed explanation-3: -Warm stream water is can affect the aquatic life in the stream. Warm water holds less dissolved oxygen than cool water, and may not contain enough dissolved oxygen for the survival of different species of aquatic life. Some compounds are also more toxic to aquatic life at higher temperatures.

Detailed explanation-4: -Rising temperatures are also likely to affect the nature of species interactions by changing resource requirements and/or uptake rates (20–22). Consequently, warming could also change the way in which biodiversity loss impacts ecosystem functioning by altering species interactions and complementarity effects.

Detailed explanation-5: -Warmer air can hold more water vapor which can lead to stronger, more intense storms. These storms can cause massive floods in various climates, which greatly shifts the natural systems of the affected areas. Again, this shift in the water cycle is particularly relevant when considering agriculture.
