The Synthesis of "nitrogen fixation"

An essential process for all life on Earth, the nitrogen cycle converts nitrogen gas into usable forms, but human activity is creating harmful imbalances.

Discover how nutrient cycles, nature's essential recycling system, sustain life on Earth and why human activity is causing them to become imbalanced.

Discover how essential elements like carbon and nitrogen are recycled through Earth's living and non-living systems in biogeochemical cycles.

Discover how plants convert sunlight into energy, a vital process that creates the food we eat, the oxygen we breathe, and helps regulate our climate.
