Animals need to breathe to get oxygen. Oxygen burns the food within their bodies and releases energy for various activities.
What?? Plants don't take in oxygen. They take in carbon dioxide and make oxygen. Reread your textbook and you will be just fine.
they have gills and take the oxygen out of the water !
Oxygen is actually breathed in by animals. It is carbon dioxide which is exhaled by animals. Plants take in carbon dioxide and give off oxygen.
Oxygen is everwhere. On earth, in the air, and on land. The animal does not need to gather oxygen.
They take in oxygen and filter water from their gills. They use the 0 from the H20 basically.
gills nose ears eyes feet
It can provide the animal with food. Plants also take in Carbon Dioxide and put out oxygen, so they sort of provide animals with air too.
I think when they receive carbon dioxide
No. No animal can live without oxygen
yes
oxygen and bacteria
Animal cells can perform metabolism with or without oxygen. In the presence of oxygen, animal cells undergo aerobic metabolism to produce energy. In the absence of oxygen, they can switch to anaerobic metabolism, which is less efficient but still allows for energy production.
