Do animals use oxygen during respiration?

Answer 1

Animals are a major group of mostly multicellular, eukaryotic organisms of the kingdom Animalia or Metazoa. While all animals may not "breathe" oxygen in the sense that may imply certain mechanical mechanisms that are used in breathing such as a diaphragm or lungs, the group does require oxygen to survive, getting it one way or another.

Answer 2

Several species of animals from the phylum Loricifera lives free from oxygen. They are extremely small and rare compared to other animal species. The reason they can live without oxygen is that they use hydrogenosomes instead of mitochondria (which needs oxygen) to generate energy.

Answer 3

yes every living thing needs oxygen except for plants. some animals dont need that much oxygen. for example bugs like lady bugs can live several days in a closed countainer. But after a long time they will die.

Answer 4

Yes of course they do, because animals are just like humans and so they do need oxygen to make energy from food. The source of energy is glucose, a simple sugar. Oxygen reacts with the glucose to produce water and carbon dioxide and release energy. This reaction, called cellular respiration, can be though of as a form of low-temperature combustion.

Answer 5

Yes, all animals need oxygen. Aquatic animals such as fish retain oxygen from water, H2O, through their gills.

Answer 6

yes... it can it actually helps the animals live better!

Hope this helps :)

Answer 7

No, animals breathe in oxygen, and give off carbon dioxide.
