Humans need oxygen to survive and think.If you dont have enoff oxygen for your brain it will stop working and you will eventually die.Humans also need oxygen sso that they can breath out carbon dioxide.If we didnt have oxygen we wouldnt have carbon dioxide.Carbon Dioxide is the thing that plants breath in.So if we didnt have oxygen plants would die.And then the animals that eat plants will die.Then the animals that eaet does animals will die.And we are omnivore(means we eat plants and animals)so if there were no plants and animals we will die of hunger That is why we need oxygen Patronum483 :)
They don't. Plants were just fine before humans were ever around.
Plants do not need oxygen (in the same way humans, for example, do) as they use carbon dioxide to form sugars for food.
humans need soil to grow trees to get oxygen and where would we be without oxygen and soil helps plants grow and not all plants need soil air plants do not need soil.
The one thing humans need in order to grow is water.
By eating plants
the reason why plants dont have skeleton because plants have stems.
The most common thing that produces something for living things is plants. Plants produce oxygen as a waste product of their food making process known as photosynthesis. Humans and animals need oxygen in order to breathe.
