Describe how humans benefit from photosynthesis

The energy we get from the food we eat originally came from plants, which absorbed energy from the sun. Photosynthesis is also important because of the oxygen it produces. They recycle the carbon dioxide we breathe out and turn it back into oxygen so that we never run out.

Explanation:

Equally importantly, photosynthesis is the source of oxygen and also removes carbon dioxide from our atmosphere. Oxygen is required for cellular respiration, the process by which food is broken down into energy. Thus, human beings are also solely dependent on photosynthetic plants for their oxygen requirements.

Explanation:

the unequal cytoplasmic division that  results  in  one egg  and three polar bodies ensures that a fertilized  egg has  ample nutrients  forits journey  to  the uterus.
