Animals use the amount of oxygen relative to their size. An elephant would need lots of oxygen, as it has larger muscles. Whereas a mouse has considerably smaller muscles, so it would require less oxygen.
yeah without the correct amount of oxygen the person will suffocate in seconds
if all the animals were gone there would be no carbon dioxide for plants and trees to take in and no oxygen would be produced.
All animals produce about the same amount of sperm.
If plants took in the same amount of oxygen as they give out during the day, life on Earth would be significantly impacted. Oxygen levels would decrease rapidly, leading to hypoxia in animals and humans. This would disrupt ecosystems, causing widespread environmental and health problems.
The same reason all land animals breathe, to take in oxygen for cell growth and repair.
Animals do not use up all the oxygen in the atmosphere because plants produce oxygen. When they breathe, plants inhale carbon dioxide (which is what animals breathe out) and exhale oxygen (which is what animals breathe in).
No, not all living things respire. Only organisms that require oxygen to generate energy through the process of cellular respiration, such as animals and most plants, respire. Some organisms, like anaerobic bacteria, can generate energy through other means and do not respire in the same way.
Yes. All animals require oxygen.
No. They breath in oxygen, like all animals.
The ultimate source of all energy in a terrestrial ecosystem is the sun. Plants capture this solar energy through photosynthesis and convert it into chemical energy, which is then passed on to other organisms in the ecosystem through the food chain.
Yes they do. All animals need oxygen.
All animals absorb oxygen and produce CO2 during respiration
