Answer:
The Earth Is Facing a Nitrogen Shortage Due to Climate Change, Study Says. Greenhouse gases, among many other pressures, are reducing access to this key nutrient in ecosystems around the world.
Step-by-step explanation:
Although nitrogen is very abundant in the atmosphere as dinitrogen gas (N2), it is largely inaccessible in this form to most organisms, making nitrogen a scarce resource and often limiting primary productivity in many ecosystems.
