what group
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.
It depends on the whale. Whales are generally divided into two groups. One is the toothed whales, which are carnivorous. The other group is the baleen whales, which use baleen to strain plankton from the ocean waters. Plankton is the term applied to an extremely broad group of tiny living things that inhabit a particular zone or depth range in the waters. And there are some that are animals, and some that are plants - which is where we were going with our explanation. The toothed whales are carnivorous, and the baleen whales strain tiny animals and plants from the ocean. Since the baleen whales eat both the tiny plants and animals, they probably aren't herbivores. A link is provided to the Wikipedia article on whales and on plankton. Surf on over and have a look.

Oxygen is in group 16 or group 6A
The -OH group is called the hydroxyl group
nekton
I think it is a Nekton because if it was Benthos it would live on the ocean floor, and Plankton are plants or plant like animals. Alligators swim freely and can't breath underwater.
Benthos is an aggrgation of organisms living on or at the bottom of a body of water: Plankton is a group of drifting organisms, and Nektons are free-swimmers unaffected by tides and currents. Therefore a shark is a Nekton.
There are over 200 species of Scyphozoa, about 50 species of Staurozoa, about 20 species of Cubozoa, and in Hydrozoa there are about 1000-1500 species that produce medusae (and many more hydrozoa species that do not).
Nekton are animals that move or swim freely in the ocean. They can live in shallow or deep water and are all shapes and sizes. Dolphins are part of the chordates group of nekton.
plankton
Yes and no. Isopoda are a big group of different animal life, some of which are plankton. Some others include regular cockroaches.
Probably in the animal plankton.
A group made up of drifting plants and animals are called plankton. Plankton is a source of food for many animals such as whales.
Plankton are a part of the Kingdom Animalia. The genus and species of plankton can vary greatly because they are a very diverse group of organisms.
Plankton is a very diverse group of microorganisms. Some plankton species are detritivores, but most are not and obtain their food from other sources.
A lionfish belongs in the fish group. Specifically, it is a type of ray-finned fish belonging to the family Scorpaenidae.
