Plants play a crucial role in the carbon cycle because they do not release carbon dioxide during cellular respiration allow carbon to enter an ecosystem via photosynthesis have special bacteria that live in their root systems are chemically converted into fossil fuels when burned

Allow carbon to enter an ecosystem through photosynthesis

Explanation:

Though plants are known to sustain life through the process of photosynthesis. In this process plants simply takes in carbon dioxide and releases oxygen.

However, this is a type of process is considered to be active during the day, while at night plants absorb oxygen and release carbon dioxide

Hence, Plants play a crucial role in the carbon cycle because they "Allow carbon to enter an ecosystem through photosynthesis."

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.
