Answer:
respiration is an intracellular oxidation process in which complex organic substances are broken down into simpler sustances with stepwise release of energy.it takes play in all organisms.it is a catabolic process.
photosynthesis is the synthesis of glucose from carbon dioxide in the presence of sunlight and chlorophyll with oxygen as a by-product.it takes place in photosynthetic plants and some bacteria and algae
aerobic respiration takes place in the presence of oxygen it occurs in all organisms CO2 and H2O are by-products it is a major source of energy for most organisms number of ATP produced is 36.
anaerobic respiration takes in the absence of oxygen it occurs in bacteria,yeast and skeletal muscles of human during exercise by-products are lactic acid ethanol and CO2
