Nitrogen (N2) makes up about 80% of the atmosphere but plants are unable to take in nitrogen from the atmosphere. Most plants can only absorb nitrogen in the form of nitrates
Animal life as we know it requires an atmosphere with sufficient oxygen. In order for plants to carry out photosynthesis, there must be a sufficient amount of carbon in the atmosphere in the form of carbon dioxide. For sustaining a stable habitable temperature, the mixture of greenhouse gases is critical.
