what is the difference between phytoplankton plankton?
131421
Phytoplankton depends on sunlight for making their food, they primarily live on the surface of the water, while zooplankton lives in the darker and colder area of the water body. Being in the category of plants, Phytoplankton releases oxygen into the atmosphere, whereas zooplankton does not have such function.

Comparing prokaryotes and eukaryotes The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. ... Prokaryotes, on the other hand, have no membrane-bound organelles. Another important difference is the DNA structure.

Spirulina grows in freshwater, Marine Phytoplankton grows in saltwater. ... Although spirulina is often classified as a blue-green-algae it is in fact not an algae at all any more, though for many years it was considered one. Phytoplankton, on the other hand, is a microalgae found in its wild form in the ocean.

Food Chain: Plankton There are many species of plankton and each has a characteristic shape. Plankton may be phytoplankton (plant-like organisms - producers) or zooplankton (animal-like organisms - consumers). Loggerhead turtles eat plankton when they are very young and small juveniles. Clams also eat plankton.

Phytoplankton or zooplankton (animal-like plankton) is eaten by small, shrimp-like animals called krill; small fish eat the krill; jellyfish eat the small fish; and finally, sea turtles eat the jellyfish. ... These decomposers feed on the decaying remains of surface plants and animals that slowly sink to the ocean floor.

The distinction between prokaryotes and eukaryotes is considered to be the most important distinction among groups of organisms. Eukaryotic cells contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not.

The individual organisms constituting plankton are called plankters. ... Planktonic organisms include bacteria, archaea, algae, protozoa and drifting or floating animals that inhabit—for example—the pelagic zone of oceans, seas, or bodies of fresh water.

Photosynthetic algae known as phytoplankton are found in both marine and freshwater environments. Most marine phytoplankton are composed of diatoms and dinoflagellates. Most freshwater phytoplankton are composed of green algae and cyanobacteria.

Zooplankton are animal plankton that are generally larger sized than phytoplankton. These animals are consumers because they must eat preformed organic compounds to survive. There are many different types of zooplankton, and their food sources vary considerably. Primary consumers are those animals that eat autotrophs.

Phytoplankton, tiny organisms that live in the ocean, are autotrophs. Some types of bacteria are autotrophs. Most autotrophs use a process called photosynthesis to make their food.

Oligotrophic lakes generally host very little or no aquatic vegetation and are relatively clear, while eutrophic lakes tend to host large quantities of organisms, including algal blooms. Each trophic class supports different types of fish and other organisms, as well.

Krill has been considered to be a zooplankton for some time. It is in many textbooks as such. Zooplankton are defined as plankton who are not primary producers (they have to eat to live and cannot make their own food through photosynthesis or chemosynthesis).

Cyanobacteria contain only one form of chlorophyll, chlorophyll a, a green pigment. In addition, they contain various yellowish carotenoids, the blue pigment phycobilin, and, in some species, the red pigment phycoerythrin.

The main difference between red brown and green algae is that red algae contain chlorophyll a, chlorophyll d, and phycoerythrin, while brown algae contain chlorophyll a, chlorophyll c, and fucoxanthin and green algae contain chlorophyll a, chlorophyll b, and xanthophylls.

Appearance. Krill species have similar characteristics and generally resemble tiny shrimp. Most species reach around 2 centimeters (0.8 inches) as adults, while the largest species can reach sizes of up to 15 centimeters (5.9 inches). Plankton, on the other hand, consists of organisms of many different shapes and sizes ...

A similarity between diatoms and dinoflagellates is that they are both types of phytoplankton that can be found in seawater. Both dinoflagellates and diatoms reproduce using photosynthesis and they both also produce significant amounts of new organisms every year.

Algae and plants are similar in that they can produce their own food from nutrients and sunlight by photosynthesis. The main difference between the two is in their complexity. Algae are simple organisms, sometimes unicellular, and even the largest types are relatively simple in structure.
