breathing their lungs and extracting it from water using gills
extract air bubbles from water
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.
Animals do not get rid of oxygen- they consume it. They get rid of carbon dioxide by exhaling it from their lungs (or gills).
Animal life depends on plants in two ways. Plants provide food for many animals and also, the plants provide oxygen for animals
one of the ways in which photsynthesis is vital to animals is that CO2 is recycled into oxygen. Without this recycling process there would be less oxygen for animals to undertake respiration.
They all need to eat and breath oxygen.
plants and animals.
I only have two ways Fungi can reproduce and so can animals Fungi are made of cells and so are animals
Through oxygen cycle. Humans and animals take in oxygen and give out carbon dioxide. Plants take in carbon dioxide and give out oxygen. This ways the oxygen is circulated in the atmosphere.
