lungs or gills
Animals breathe in oxygen in the air.
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).
animals
Some animals that use air tubes, or gills to breathe are mollusks, fishes, crustaceans, insects, and amphibians. Other animals use things like blowholes or breathe.
Yes flatworms are animals who have soft bodies and use their skins to breathe
Frogs and other amphibians.
they breathe
We eat them or breathe the oxygen they produce.
Plants and animals have a synergistic existence, meaning that they benefit from each other in their survival. When animals breathe in air, their bodies remove the air's oxygen and use it for fuel. When they breathe out, they breathe out carbon dioxide. Plants love carbon dioxide. They take it and convert it back to oxygen which they then disperse into the air for animals to breathe. Your answer is "carbon dioxide".
they breathe in the same way as daytime animals
Animals breathe in oxygen from the air through their respiratory system. They use oxygen to fuel their cells and produce energy through a process called cellular respiration. Then, they release carbon dioxide, a waste product, back into the air when exhaling.
Animals breathe out carbon dioxide, which is used by plants during photosynthesis to produce oxygen and glucose. This exchange of gases between animals and plants is essential for the Earth's ecosystem.
