They eat plants or animals (or both) and the breathe with lungs (or gills in the case of fish). A vertebrate is any animal with a backbone. People dogs cats, cows, fish, monkeys, whales, dolphins, frogs, gerbils, bats and so on.
Vertebrates are consumers in the food chain. Herbivores are primary consumers, feeding on plants, where carnivores are secondary consumers, feeding on herbivores for energy.
Horses have lungs and nostrils just like us humans to obtain oxygen. They also have stomachs like us to digest food. Humans and horses are both mammals and vertebrates so we're relatively the same
they are carnivores so they get food by killing other mammals and oxygen by inhaling with there lungs
Echinoderms get their food and oxygen for energy. They ues tube feet to obtain oxygen from the water.
They depend on the constant waterflow of the ocean through their bodies to obtain food and oxygen and remove wastes.
Human cells obtain the much-needed food and oxygen via the bloodstream.
They hunt and breath through their nose.
respiration
Animals inhale air in order to obtain the oxygen they use for extracting energy from food
The amphibian's heart does pump out a mixture of oxygen-rich and oxygen-poor blood. They are vertebrates, and this is how vertebrates' circulatory systems work.
Our body obtain oxygen to our body by breathing.
They are anaerobes and do not need oxygen. They are consumers and make energy by fermentation.
I believe the process is called,"Photosynthesis"! Plants do not obtain oxygen they produce oxygen through a process called photosynthesis. The sun produces energy and they change carbon dioxide and water into food oxygen is a byproduct of this process.
