Document Summary
Introduction to life processes: you should know the definitions of consumer and producer. Light energy from the sun is no longer necessary for the reaction to take place. We are measuring how much carbon get produced in that area each year: tells us how productive an area is, most important production areas. Shelf plankton over the continental shelf: 90-270 gc/m^2/yr: open ocean: 1-180 gc/m^2/yr, areas like the coral reef and kelp bed have a very high productivity level. That on the same level as tropical rain forests. In the real system, energy isn"t transferred in a simple linear chain. This chemical energy (carbs) is passed on to consumers. The consumers eat this, use the energy for growth and reproduction. The correct answer is: coral reefs and kelp bed have the highest net primary productivity and the open ocean has the lowest. Carbon dioxide in the atmosphere is dissolved in the ocean and taken up by phytoplankton through photosynthesis.
