Which action would allow you to distinguish between transpiration and
evaporation in a model ecosystem?

a. remove all the soil from the model ecosystem.

b. make a second terrarium that has no plants but is otherwise
identical.

c. remove all the animals from the model ecosystem.

d. make a second terrarium that has no animals but is otherwise
identical

The correct answer is option B. "Make a second terrarium that has no plants but is otherwise identical".

Explanation:

Transpiration and evaporation are two processes that are key for the hydrological cycle, allowing the return of water to the atmosphere in a gaseous form. In the two processes water is evaporated, with the main difference that water evaporation occurs directly from the soil, and transpiration is a biological process at which water is evaporated from plant cells. Therefore, if it is needed to distinguish between transpiration and evaporation in a model ecosystem, make a second terrarium that has no plants but is otherwise identical will be a valid approach.

stratosphere: as the altitude increases, the air temperature increases. the stratosphere has a layer of ozone, called the ozone layer. this layer absorbs most of the ultraviolet radiation from sunlight. this results in the stratosphere being warmer.
