Answer:
Target plant biomass decreased and neighbor plant root biomass increased.
Explanation:
As the percentage of a target plant's tube open to neighbors' roots increased, <em>target plant biomass decreased and neighbor plant root biomass increased</em>. The study was designed to investigate the relationship between neighbor root biomass and belowground competition. When the number of target plant's tube open to neighbors' roots increased, target plant biomass decreased and neighbor plant root biomass increased.
Synonyms help us connect unknown words with known words. For example, one may not know the meaning of the word "nefarious" when used in this context: "The offense was more nefarious than previously thought." If we replace "nefarious" with "evil" or "wretched" the meaning is more comprehensible to those who don't know the meaning of "nefarious": The offense was more evil (wretched) than previously thought."
I hope this helps, I used nefarious as a somewhat uncommon term to better illustrate my point, and to explain why we use synonyms to learn new words. Simply put, synonyms bridge us to the unknown using the known as solid ground build from.
