Question 1 Report

Respiration is important in living organisms because it

Answer Details

Respiration is the set of chemical reactions in cells that break down nutrient molecules and release energy for the organism's other processes, so it matters because it releases energy from nutrient molecules. It does not detect light or sound (that is sensitivity) and it breaks molecules down rather than building them up. Although carbon dioxide is later removed from the blood, that removal is excretion, not the purpose of respiration itself.
