Part 1 and Part 2 NEEDS TO BE COMPLETELY SEPARTED ON SEPARTATE PAGES, EACH ONE NEEDS THERE OWN REFERENCES CONNECTED TO PART 1 AND PART 2

PART 1
Life on Earth evolved in the ocean and it may have been “seeded” in the oceans but comets or meteors splashing into those ancient oceans. Life existed in the ocean for almost 3 billion years BEFORE it moved out on to land.
Respond to the following:
A)What might comets and/or meteors have had that might have “seeded” life in the oceans? (They did NOT bring whole organisms like bacteria).
B)What had to happen on Earth before life could move out of the oceans (the crust of the Earth had long since have cooled off).Hint it had to do with the conversion of the atmosphere due to photosynthesis.

PART 2 (Separated with references completely separated from PART 1)
Define biological productivity.? When a scientist says productivity is a rate, what does she or he mean? List several factors that influence productivity in various ocean environments (the surf zone, mid-ocean and the deep abyss). How do these areas differ in terms of productivity and why?
Read the attached article about the Arctic Plankton Bloom it gives good insight into this topic. In addition read the recent article on the changes in the Arctic Food Chain. If you really read it and think about what causes surface biological productivity you will find that the argument made in this article makes NO sense.
