Their beak??
A penguin is a flightless bird it use lungs for in take of Oxygen in its body.
they use its beak to get food
Birds take in more oxygen per breath compared to mammals, as they have more efficient respiratory systems. Birds have air sacs that allow for a more continuous flow of oxygen through their lungs, increasing the amount of oxygen they can extract from each breath.
Leaves are a part of a plant. Plants TAKE IN carbon dioxide and GIVE OFF oxygen.THEREFORE, leaves do not give oxygen. :D Leaves are however key part of the photosynthesis process.
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.
do plants switch how they use oxygen day and night?
There is no oxygen in space. Astronauts have to take oxygen with them.
Aerobic organisms, such as mammals, birds, and many types of bacteria, can use gaseous oxygen in their metabolism. This process is known as aerobic respiration, where oxygen is used to produce energy through the breakdown of organic molecules.
Heracles shook a rattle that Athena gave him to get the birds to take flight and then shot as many of them as he could.
Rockets designed for space travel use oxygen as part of their fuel systems because the oxygen aids the combustion by acting as an electron acceptor. Liquid oxygen may also be used in rocket fuel sometimes.
Most animals, including mammals, birds, fish, insects, and some reptiles, use oxygen for respiration. Additionally, many plants also require oxygen for cellular respiration, although they primarily produce oxygen through photosynthesis. Microorganisms like bacteria and fungi can also use oxygen for growth and metabolism.
