yes.
Protists are single celled organisms which include both animal-like cells and also plant-like cells. The plants are the reason such an ecosystem can sustain itself. The plants manufacture food and the animals either eat the plants or recycle dead cells.
Any closed container demonstrates this, since the water will become green and stay that way for as long as the jar remains undisturbed. This theoretically can be thousands of years.
After this time, the organisms may have evolved species found nowhere else on earth, except for inside the jar. They will be perfectly adapted to jar existence and could probably live nowhere else. This is principally how species in the real world become extinct. Someone or something breaks their jar.
Algae is a protist. All algae contains chlorophyll.
plants contain cellulose in their cell wall while fungi contains chitin as a major component of its cell wall.Besides fungi are absorptive heterotrophs while plants are photosynthetic autotrophs.fungi lacks centrioles and contains chitin in its cell wall(as described earlier) but certain protists have centrioles and produce cellulose in their cell wall.some protists also contain some pigments like Chl.a Chl.b caroteins etc while fungi does not.Due to these reasons Fungi has separate kingdom.
plantae, monera and protista
No, protists are generally unicellular.
Protists are eukariyotic creatures.So they have nucleii.
THEY ABSORB NUTRIENTS FROM AIR

Algae is a protist. All algae contains chlorophyll.
The Organ Level
Protists are useful in the ecosystem. They are used in some high blood pressure medicines. They are also used by fish breeders to feed small fry for their first few days of life.
the two characteristics shared by all three groups of protists is protozoa and algae
Protists play important roles in aquatic ecosystems as primary producers, consumers, and decomposers. They are crucial in nutrient cycling and serve as food sources for many organisms in the food chain. Some protists also form symbiotic relationships with other organisms, contributing to overall ecosystem diversity and stability.

Phylum Zoomastigina contains flagellated protists, also known as zooflagellates. These protists are typically free-living and can be pathogenic, causing diseases in animals and humans. They have whip-like flagella used for movement and are often found in aquatic environments.
Protists play the part of eating bacteria in a fresh water ecosystem. They also eat other particles that contain bacteria hence helping in keeping the number of bacteria in the water in check.
The protists do not have much in common besides a relatively simple organization[3] - either they are unicellular, or they are multicellular without specialized tissues. This simple cellular organization distinguishes the protists from other eukaryotes, such as fungi, animals and plants. Protists live in almost any environment that contains liquid water. Many protists, such as the algae, are photosynthetic and are vital primary producers in ecosystems, particularly in the ocean as part of the plankton. Other protists, such as the Kinetoplastids and Apicomplexa are responsible for a range of serious human diseases, such as malaria and sleeping sickness.
