What is ecology?

500

A model contrasting renewable and nonrenewable resource impacts on sustainability.

What is the IPAT model?

500

This cycle is unique for lacking a gaseous component and primarily moves through rock and soil.

What is the phosphorus cycle?

500

This part of the nitrogen cycle converts nitrogen gas to ammonia, making it usable for plants.

What is nitrogen fixation?

500

The process by which water moves from Earth's surface into the atmosphere, primarily through evaporation and transpiration.
