∙ 8y agobecause it is a gas that helps living life forms such as us and animals survive. and the stuff we breath out is carbon dioxide which is also necessary because plant breathe that in and breathe out oxeygen which helps us survive. that why its necessary and that's why we need plants.
Also, symbollically, it seems to be the essence of 'the breath of life', which God breathed into Man upon his creation.

∙ 12y agoWell its because you need oxygen throughout your body including your blood stream and if you don't have any oxygen in your body you die bc also all your major organs

Bacteria that can survive without oxygen are?
If they CAN survive without oxygen, they are called facultative anaerobes. In other words, these can survive with or without oxygen.If they CAN ONLY survive if there is no oxygen, they are callled obligate anaerobes. In other words, these can only survive if there is no oxygen.

Plants need oxygen in order to survive, and is a part of the photosynthesis process. Plants also need carbon dioxide and nitrogen to survive.
