1. Ecosystems in the Ocean Is a grain farm on land more like a wild terrestrial or oceanic ecosystem? (Hint -- why do we fertilize a farm when we don’t need to fertilize a forest?)

2. What is an ecosystem?

3. How is the land different from the ocean? This changes EVERYTHING!

4. Differences between land and sea Tall trees Small plankton

5. How this changes ecosystem! Big plants mean big herbivores.

6. Small plants mean small predators and many links in the food chain!

7. Land: Grass => Antelope => Lion Grass => Bunny => Fox Ocean: Small Phyto’s => small Zoo’s => to bigger Zoo’s => And: Big Phyto’s => Big Zoo’s => small fish (anchovies) => bigger fish (blues) => biggest fish (tuna)

8. Every step in chain, 90% of energy lost! Where do we eat on food chain?

9. What controls Primary Production & Biomass? Land has 50x biomass of ocean, but same Primary Production. Why different?

10. Cycling time on land vrs. sea

11. Next parts of biology section: 1.Who are the players? 2.How do food chains work? 3.How is PP and biology controlled by physics?
