Give a scenario where a density-independent factor has an effect on a density-dependent factor

i think it is true in my reasonment ..

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

i think the answer is 95 hope this
