The continuous flow of elements & compounds between organisms & the earth

Nutrients- inorganic substances that organisms require to live

Organic substances break down through decomposition leaving behind inorganic substances eventually brought to surface by upwelling.

Fundamental element (carbon is in all living things)

Carbon forms the basis for chemical energy and for building tissues.

Carbon dioxide gas dissolves into the ocean (a CO2 storage tank “Carbon Sink”)

Decomposition of organisms releases it Calcium carbonate Much is concentrated in the deep sea Major contributor to global warming

Required by organisms for proteins ,chlorophyll, and nucleic acids.

Must be converted to a usable form by bacteria AmmoniaNitratesNitritesNitrogen gas

Used in the ATP/ADP cycle (Energy) Part of DNA Makes up bones & teeth when combined

with calcium carbonate Fertilizer

Silicon exists as silicon dioxide aka silica.

Used by diatoms and radiolarians (types of plankton) to build shells and skeletons.

Most sand is silica due to its abundance in rocks and resistance to being broken down completely.

1. Which gas needs to be converted by bacteria before we can use it?

2. How do organisms use nitrogen?

3. Why is phosphorous essential to life?

4. Why is Silicon important to some marine organisms?
