Weight of plankton?
Asked in Microbiology, Weight and Mass, Plankton
What is the weight of a single plankton?
We have a problem weighing a single plankton. And it's not because we don't have accurate machines (scales) to do that. It's because there are so many kinds of plankton. Here's a most important fact: plankton is a term that refers to aquatic life that lives in certain zones of the open ocean or a lake. It's not a single living thing or a small group of things, but is comprised of many thousands of types of organisms. They range is size tremendously! Because plankton represents a wide group of organisms, we can't discern "the weight of a single plankton" as was asked. A single amphipod may weight a ten thousandth of a gram, but there are bacteria that are plankton - the bacterioplankton - and they are "electron microscope small" and weigh far less than a microgram.
