Most reptiles use diffusion through the skin to obtained oxygen.
Amphibians can absorb oxygen through their skin - reptiles need to physically breathe.
Reptiles do need oxygen
No, birds and other reptiles like crocodiles also breathe air. Insects absorb air through their skin.
Plants primarily absorb carbon dioxide (CO2) during photosynthesis and release oxygen as a byproduct. They do not absorb oxygen in the same way that they absorb CO2. Oxygen is mainly taken in through plant tissues for respiration, where it is used to break down sugars and produce energy.
No, cardboard does not absorb oxygen. Cardboard is made from cellulose fibers and does not have the ability to absorb gases like oxygen.
They absorb the oxygen from the lungs and carry it until it is used.
Its roots can absorb oxygen from water
the answer to that is RESPIRATION
Reptiles don't get oxygen from the water. All reptiles have to come up to the surface to breathe, but can hold their breath a long time.
Plants absorb Co2. Carbon dioxide. Which is Carbon and oxygen. The carbon is used in the plant and the oxygen is released, (or reflected as you could say).
Its roots can absorb oxygen from water
the answer to that is RESPIRATION
