Answer:
A terrarium with a plant and a snail
Explanation:
This is because snail uses oxygen for cellular respiration and releases carbondioxide as by product.
Where as plants uses carbondioxide exhaled for photosynthesis in the presence of light energy and chlorophyll with water to produce glucose and oxygen. Therefore cycle if oxygen and carbondioxide gases is continuous.
In doing the experiment in root pressure, it is always a priority to know and apply precautions in doing experiments. It is best to consider precautions that will be of help and to prevent any damage that could occur. Precautions that are needed to be applied: Safety handling has always been a priority in handling experiments because if this is not done correctly, a lot of things may go wrong. Follow the correct procedure in order to have the correct outcome because not following the instruction could fail the experiment. Lastly, materials needed should be organized and complete in order to provide the needs of the experiment.
