They absorb the oxygen from the cell which gets its oxygen from the blood
Our body obtain oxygen to our body by breathing.
Yes, you could still calculate Elodea's rate of photosynthesis by measuring the change in dissolved oxygen in the water over time. The presence of single-celled protozoans would not significantly affect the ability to measure the rate of oxygen production by the Elodea.
Crustaceans obtain oxygen through gills.
Protozoans are single-celled organisms that belong to the protist kingdom. They are mostly microscopic and exhibit a wide range of shapes and structures. Protozoans are known for their ability to move using cilia, flagella, or pseudopods, and they obtain nutrients through various modes such as phagocytosis or diffusion.
Who is "they" ?
you obtain oxygen from your lungs you could breath through your nose and through your mouth
multicellular organisms obtain their oxygen through the respiratory system
We obtain oxygen by breathing in fresh air. Carbon dioxide comes out of us.
No. The skeleton dose not get oxygen
Pterodactyls do not obtain oxygen at this time because they are extinct. While they existed, they probably obtained oxygen in the same way that birds today obtain it through the use of lungs.
Plants obtain oxygen during photosynthesis from water molecules.
No, not all protozoans are prokaryotic and autotrophic. Protozoans are eukaryotic organisms that can be autotrophic or heterotrophic. Autotrophic protozoans can photosynthesize like plants, while heterotrophic protozoans rely on organic matter for nutrition.
