human because plants breath carbine dioxide
All animals and plants. The air is 78% nitrogen.
nitrogen cycle
The nitrogen cycle is the process by which nitrogen moves through the environment. Nitrogen gas in the air is converted into a form that plants can use by bacteria in the soil. Plants then take up this nitrogen to grow. When plants and animals die, bacteria break down their remains, releasing nitrogen back into the soil. This cycle continues as nitrogen is recycled between the air, soil, plants, and animals.
Plants use the decaying remains of animals for nutrients. Animals use plants for nutrients and air. Plants also need air in order to survive. Air uses plants to be produced. -CO

It evaporates and recycles within the air. It is part of the weather cycle.
One resource that is constantly cycling through the environment is water. Another resource is air for plants and animals to breathe.
Plants and animals are both complex organisms that share in a cycle of carbon dioxide and oxygen. Animals breathe out carbon dioxide when they respirate and plants take that in through their leaves and then emit oxgen which animals inhale. And the cycle begins again.
From plants or air.
Animals are useful for plants bacause tja e plant needs carbon in night and animals do need
photosynthesis
In the atmosphere, carbon is attached to the oxygen gas molecules and with the help of the sun and photosynthesis; the C02 gas is pulled from the air to make plant food from carbon molecules. Through food chains, the carbon in the plants moves into the animals that consume the plants, and animals eat other animals are getting the carbon from their food. In basic terms: carbon moves from plants to animals, and into the ground and reenter the atmosphere. The 02 gas is produced in the plants which release it into the air and consumers inhale it in; and/or the 02 gas in the atmosphere goes into the ground.
