How does photosynthesis benefit heterotrophs?

Photosynthesis benefits heterotrophs in several different ways. First, photosynthesis consumes carbon dioxide (a waste product of respiration) and produces oxygen (necessary for respiration). Heterotrophs therefore depend on photosynthesis as a source of oxygen. read more

Heterotrophs and Photosynthesis In contrast to autotrophs, heterotrophs survive through respiration, using oxygen and an energy source (carbohydrates, fats or protein) to produce ATP, which powers cells. read more

As heterotrophs cannot fix carbon or generate energy from non organic means Photosynthesis in plants is the only way through which energy enters the food chain for them. read more
