A) If you have a mass of 65 kg, determine the force of gravity acting on you if you were on the surface (in other words the top cloud layers) of Uranus
and Neptune. (Note: You are calculating your weight at each location. You
can also look up the masses and radii of each object in question.).
b) Compare this to the force of gravity acting upon you if you were on the
surface of the Earth. (Note: You are calculating your weight at each
location. You can also look up the masses and radii of each object in
question.). This question will be worth 19 points.
Note: For the calculation please image your work and upload it to the
dropbox provided for this question.

bacteria that live on the ocean floor are sustained by phytoplankton. phytoplankton, microscopic marine photosynthetic organisms, have a vastly significant role to play not only in the marine food web of which they’re part of, but also on a more global scale. despite their infinitely small size in comparison to other marine organisms, these tiny creatures occupy an immensely important ecological niche: they are the foundation of the marine food web, and as primary producers, play key roles in supporting all other organisms in the marine environment, as well as in the regulation of the earth’s climate through the sequestration of carbon, oxygen production, and other related processes. phytoplankton account for roughly half of all global primary productivity; therefore, their significance extends far beyond the marine environment alone. there is an intriguing sense of irony in the realization that these tiny living beings that often live out their existence unnoticed and undetected by the rest of the world, have such a far-reaching impact on the lives of virtually all other living organisms on the planet, particularly on those in the marine environment. the world that we have become accustomed to has been and is continuously shaped by the workings of these miniscule yet vital “plants of the sea”.

hope this !
