A living anything needs food and lots of living things need oxygen. So, yes, embryos need food and oxygen too.
Plants need oxygen for aerobic respiration. Although photosynthesis produces oxygen as a waste product, and this oxygen is used for aerobic respiration, plants still need oxygen to survive, as the oxygen produced as a waste product of photsynthesis is not always sufficient to supply the plant with all the oxygen it needs.
one uses oxygen to get energy and the other uses yeast!Fermentation does not need oxygen. Aerobic respiration need oxygen
most are aerobic - need oxygen. there are some that are anaerobic - grow without oxygen
Trees do not consume oxygen. They consume carbon dioxide, and give off oxygen.

Worms are parasites. They take nutrients away from the horse. We deworm them, to get rid of the parasites.

Many algae are microscopic and are microorganisms put do not live on any other organisms. Mosquitoes need blood and will bite humans but they can be seen. They are parasites since they need a blood meal.

Reptiles do need oxygen
While our understanding has been that 'Every single animal needs oxygen to survive', Scientists have just discovered the first multicellular animals that can survive entirely without oxygen. They live in the L'Atalante Basin in the Mediterranean Ocean, a place with salt brine so thick it doesn't mix with oxygen-containing waters above.
If the vehicle was built with an oxygen sensor, you will need an oxygen sensor.
Floran fish need oxygen other wise it will death . so always need oxygen
