What does the process of photosynthesis produce that all living organisms need?
organic compounds especially sugars- the source for energy for most living organisms not all.
Plants are called producers because they are able to produce energy and carbon for themselves from non-living sources through a process known as photosynthesis. In photosynthesis, plants use sunlight and carbon dioxide to produce organic compounds. These organic compounds become the source for many other organisms within an ecosystem.
No, not all living organisms undergo photosynthesis. Only phototrophs (photosynthetic autotrophs) such as plants, algae, and many forms of photosynthetic bacteria undergo photosynthesis. All other organisms live by eating autotrophs or other organisms that have eaten autotrophs; these organisms are heterotrophs. There are a few specialized organisms (which may live where no light shines) that use a process called chemosynthesis to get their energy; these organisms are called chemotrophs.
