Animals need oxygen from air to carry out the reactions that release and transform energy from food . Carbon dioxide is released as a waste product during these processes. In mammals, including humans, air enters the body through the nose and mouth, and moves into the lungs.
What process does require oxygen?
| Aerobic Anaerobic | Reactants Glucose and oxygen Glucose |

In which process do animals use oxygen?
Animals and all life that requires oxygen to survive, use glucose and oxygen in aerobic cellular respiration . Aerobic cellular respiration breaks down glucose molecules, storing the energy released during the process in molecules of ATP (adenosine triphosphate), which provide the energy needed for cell(s) to do work.
What process done by plants and animals requires oxygen?
photosynthesis , the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
Which animal can live without oxygen?
A tiny parasite called Henneguya salminicola is the first known multicellular animal that can survive without oxygen, according to a study published Tuesday in the journal Proceedings of the National Academy of Sciences by researchers at Tel Aviv University.
Why is oxygen important to humans and animals?
Oxygen helps organisms grow, reproduce, and turn food into energy . ... Oxygen gives our cells the ability to break down food in order to get the energy we need to survive. Although other animals may use different organs to breathe with, they all get oxygen into their bodies through respiration.
What type of respiration do humans have?
Respiration process that occurs in the presence of oxygen is called aerobic respiration , generally seen among humans. But in certain organisms like bacteria and algae, respiration occurs in the absence of oxygen, called anaerobic respiration.
What is presence of oxygen?
adjective. (of an organism or tissue) requiring the presence of air or free oxygen for life. pertaining to or caused by the presence of oxygen. of or utilizing the principles of aerobics: aerobic exercises; aerobic dances.
What is absence of oxygen?
One occurs in the presence of oxygen (aerobic), and one occurs in the absence of oxygen ( anaerobic ).
What is oxygen cycle with diagram?
What is oxygen cycle explain with diagram? The cycle of oxygen describes the different forms in which oxygen is found and how it moves on Earth through various reservoirs . Three major oxygen reservoirs are present: the atmosphere, the biosphere, and the lithosphere.
Do plants take in oxygen?
Most folks have learned that plants take up carbon dioxide from the air (to be used in photosynthesis) and produce oxygen (as a by-product of that process), but less well known is that plants also need oxygen . ... So plants need to breathe — to exchange these gases between the outside and the inside of the organism.
What is oxygen cycle and its importance?
The oxygen cycle is an essential biogeochemical cycle to maintain the concentration and level of oxygen in the atmosphere . The oxygen cycle is one of the main reasons for the existence of life on earth. ... They release carbon dioxide as a by-product into the atmosphere and which is again used by plants.
What animal has 32 brains?
The leeches that I have driven several hundred miles to encounter are freshwater, bloodsucking, multi-segmented annelid worms with 10 stomachs, 32 brains, nine pairs of testicles, and several hundred teeth that leave a distinctive bite mark.
Can we live without oxygen?
Without oxygen, the human body can only survive for a few minutes before the biological processes that power its cells begin to fail. ... Without oxygen, the human body can only survive for a few minutes before the biological processes that power its cells begin to fail.
Which animal can live without head?
Cockroaches are infamous for their tenacity, and are often cited as the most likely survivors of a nuclear war. Some even claim that they can live without their heads. It turns out that these armchair exterminators (and their professional brethren) are right. Headless roaches are capable of living for weeks.
Why oxygen is very important to your body?
Our body needs oxygen to obtain energy to fuel all our living processes . Carbon dioxide is a waste product of that process. The respiratory system, with its conduction and respiratory zones, brings air from the environment to the lungs and facilitates gas exchange both in the lungs and within the cells.
