The Volcanoes That May Have Started Life on Earth
The nitrogen cycle is essential to life on Earth, but biological nitrogen must be fixed before it can be used. Scientists aren't sure how the first nitrogen became available... but it might have been volcanoes.

Natural Ecosystem Change
In this video Paul Andersen explains how the Earth's climate will natural change due to interactions between the Sun and Earth, volcanism, and plate tectonics. Species may go extinct leading to adaptive radiation or may move to a...

Biogeochemical Cycling
Paul Andersen explains how biogeochemical cycling is used to move nutrients from the environment into living material and back again. He explains the water cycle, the carbon cycle, the nitrogen cycle and the phosphorus cycle. He also...

Biogeochemical Cycles
In this video Paul Andersen explains how biogeochemical cycles move required nutrients through the abiotic and biotic spheres on our planet. Matter on the Earth is conserved so producers must receive required nutrients through the water...

BIOLOGY - Environment - Nitrogen Cycle
Nitrogen makes up 78% of the air, however neither plants nor animals can take nitrogen directly from the air because nitrogen is so unreactive. The nitrogen cycles shows the movement of nitrogen through the environment. Nitrogen is...
