Animals get their oxygen from ambient air, the air around us. Depending on the animal and whether it's carnivorous, omnivorous or herbivorous would determine where exactly it gets it's food from.
breathing
Different animals breathe in different ways. there are body coverings, tubes in their body, and lungs
Animals breathe in oxygen in the air.
What do you think will happen to animals and humans if the amount of oxygen in the air is reduced?
Animals need AIR to breath in - AIR is made up of about 80% Nitrogen and 20% Oxygen. The animals use the Oxygen in the AIR.NOTE if an animal were to breath 100% Oxygen this would eventually kill it, Pure Oxygen is toxic.They need to breath AIR.
Fish using their gills to get oxygen from water.Mammals and most other animals using some kind of opening in their skin to inhale the oxygen from the air.
the air
plants give off oxygen and so do animals and that's how it gets in the air
All animals need oxygen to live.
no
Before the algae evolved, the oxygen % in the air was only a few%. After the algae, the % grew to over 20%. Which is why in the Carboniferous had giant plants and some large animals. Since then, the oxygen % of the air has diminished.
many land animals get oxygen by breathing air into their lungs,like you do .but not all animals get oxygen this way. different structures for getting oxygen.
Yes organisms take oxygen from the air and aquatic organisms take oxygen from the water using their gills. Some do. Most only from one or the other. For example a tuna fish gets pretty much all its oxygen from oxygen dissolved in water. Humans get all our oxygen from the air. Mudskippers get oxygen from both. Yes. Land animals take in oxygen that plants release using their noses. On the other hand, aquatic or marine animals take in oxygen using their gills.
No, animals get the Oxygen they need from breathing in air as part of the process of respiration, this has nothing to do with digesting food.
