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.
No, a diverse ecosystem with a variety of organisms is necessary for long-term stability and sustainability. Protists alone would not be able to maintain crucial ecological functions like nutrient cycling, energy flow, and predator-prey interactions. A lack of biodiversity would leave the ecosystem vulnerable to disruptions and unable to adapt to changing conditions.
Yes, most protists have a nucleus. Protists are eukaryotic organisms, meaning they have a defined nucleus that contains their genetic material. However, there are some protists that lack a true nucleus and are considered primitive.
Protists that contain chlorophyll are known as photosynthetic protists. They can carry out photosynthesis to produce their own energy using sunlight, much like plants. Examples include algae and certain types of phytoplankton.
Protists play various roles in the environment, such as being important components of the food chain in aquatic ecosystems, serving as primary producers through photosynthesis, and acting as decomposers that break down organic matter. Some protists also form symbiotic relationships with other organisms, influencing nutrient cycling and ecosystem dynamics. However, certain protists can also cause harmful algal blooms or diseases in humans, animals, and plants, impacting ecosystem health.
Yes, some bacteria can decompose protists by breaking down their organic matter for nutrients. The process of decomposition helps recycle organic materials back into the ecosystem.
The domain Eukarya contains both unicellular (e.g. protists) and multicellular (e.g. plants, animals, fungi) organisms.

No, protists are eukaryotic organisms and have cells with nuclei. The nucleus in protists contains their genetic material and helps regulate cellular functions.

The category that contains the most organisms is domain, with Eukarya being the largest domain and containing a wide variety of organisms including plants, animals, fungi, and protists.

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.

Yes, there are protists in the Alaskan tundra. Protists are a diverse group of eukaryotic microorganisms that can thrive in extreme environments like the tundra due to their adaptability and resilience. They play important roles in nutrient cycling, food webs, and overall ecosystem function in tundra ecosystems.
