Algae-Seaweed-Sea Grass

In long past years most students of biology heard the same story over and over......Every living thing depends of the energy of sunlight.   Now  we know photosynthesis is not necessary, and impossible in the deep ocean, and that chemical energy systems from the earth itself can power life.  We still don't know what percentage of life is powered by the sun and what gets energy in other ways but here on the surface it looks like photosynthesis is doing all right.....I noticed it's doing really well with my lawn (why I still have one of those I don't know).
In Puget Sound there are some 500 or more species of seaweeds, two species of sea grasses plus an unknown but large number of algal plankton species. The images below attest to the diversity of the seaweeds and phytoplankton but just scratch the surface. For a more in depth look (only about knee deep) check out the presentation Algae and Seaweeds under Buzz Links on this page.
