Answer:
Plants take in carbon and let out oxygen.
Explanation:
Carbon and cellular respiration has to do with those cycles because plants which do cellular respiration as well as all living things take in either oxygen or carbon and let either one of them out.
As Marta wants to explain the water cycle, it is best to do it via video simulation of the cycle. The correct option is C.
<h3>What is water cycle?</h3>
The water cycle depicts the consistent flow of water within the Earth's and atmosphere's ambience.
It is a complicated system with numerous mechanisms. Liquid water evaporates into water vapor, condenses into clouds, and falls back to earth as snow and rain.
Marta's best bet for explaining the water cycle is to use a video simulation of the cycle as video is the best way to understand the process.
Thus, the correct option is C.
