This is a very informative powerpoint with large, interesting pictures, that I subdivided into small sections with pre/post anticipation guides. Here is an outline of the topics covered in the PPT:
1.) Photosynthesis and Cellular Respiration Introduction (Heterotrophs, autotrophs)
2.) What is Plankton (Plankton, holoplankton, meroplankton, phytoplankton, zooplankton, photic zone, aphotic zone, etc)
3.) Plankton Distribution (latitude, productivity, upwelling, marine snow, etc)
4.) Trophic Pyramids / Food Webs (10% flow concept, food web, food chain, biomass, etc)
I hope you enjoy this. Made by a teacher who LOVES the ocean, and is a lifetime member of the Florida Marine Science Educators Association. Thank you for the purchase!
