Answer;
Hot & Dry conditions
Explanation;
-C4 is the alternative pathway of Calvin cycle (C3 cycle) taking place during the dark phase (light-independent stage) of photosynthesis. In the C4 cycle the first stable compound is 4 carbon compound, namely oxaloacetic acid. Hence it is called C4 cycle. It is a process of carbon dioxide fixation.
-C3 plants have the disadvantage that in hot dry conditions their photosynthetic efficiency suffers because of a process called photorespiration. When the CO2 concentration in the chloroplasts drops below about 50 ppm, the catalyst rubisco that helps to fix carbon begins to fix oxygen instead.
-The problem of photorespiration is overcome in C4 plants by a two-stage strategy that keeps CO2 high and oxygen low in the chloroplast where the Calvin cycle operates.
Due to the fact that they had believed that the world was the center of the universe and refused to believe otherwise.
Although it was more of a biblical Catholic Church going against the model, the general public was mainly dictated by the Catholic Church. Since this was introduced in a religious period, it was opposed because it basically stated that the scripture was wrong. Scientists also were looked down upon at the moment as their findings would basically instigate that the Church’s teaching was incorrect.
Hope this helps!
