Background

Why is the sky blue? Why is the grass green? So many questions

ponder through each individual's head. The main question of the experiment

performed is "Why are plankton so small?" As a group, the main concept that

was explored was how the Nutrient Feeding of Phytoplankton leads to its

size. The Independent Variable of the experiment was the Surface Area to

Volume Ratio, the Dependent Variable was the Percent Fed, the Control was

the Untreated Plankton, and the hypothesis proposed acknowledged that if

the Surface Area to Volume Ratio is large, then it will be 100 percent fed.

What is plankton? According to the handout "Plankton," "the word

plankton means 'that which is made to wander.'" It is the primary producer

in the ocean and can be found in the form of an animal, known as

zooplankton, and in the form of a plant, known as phytoplankton. Plankton

is microscopic and can be found floating on the surface of the ocean with

the currents. Three things can classify plankton: type, lifestyle, and

size. Phytoplankton is plant plankton and Zooplankton is animal plankton.

Meroplanktons are plankton that spend a mere portion of their life as

plankton. Holoplanktons are plankton that spend their whole life as

plankton.

There are many different types of sizes of plankton everywhere in our

ocean waters. And there are also different classifications of plankton such

as Macroplankton and Holoplankton. Holoplankton spends their whole life in

a plankton community. Macroplankton is also a classifacation and they are

most likely larger than one centimeter. Others that are also phytoplankton

are Diatoms and dinoflagellates witch are both plant plankters. All theses

phytoplankton are a big key in marine life of today. They are the key to

preventing global warming in many cases. These singled cell organisms are

microscopic but size is not a factor in marine life. All phytoplankton

inhabit three quarters of the earth. " Every drop of water in the top 100

meters of the ocean contains thousands of free floating microscopic flora

called phytoplankton" (The Oceans.). Phytoplankton is all over the place

and has a drastic affect on the ocean and the things that happen in it.

Plankton most likely reproduces in the springtime. Because the
