they get some food in the organisms known as hosts
cytostome
they can move toward food on their own
Protozoans that cannot move are called sessile protozoans. These organisms are typically attached to a substrate and rely on external factors, such as water currents, to bring food to them.
The fingerlike projections of cytoplasm used by some protozoans for movement and obtaining food are called pseudopodia. These structures help protozoans to extend their reach and capture food particles in their environment through a process known as phagocytosis.
All protozoans are considered heterotrophic, meaning they need to take in food. They can do this through different methods, such as phagocytosis, absorbing nutrients through their cell membrane, or feeding on other organisms.
Understanding protozoans is crucial because they play significant roles in ecosystems, serving as both predators and prey in food webs. They can also impact human health, as some protozoans are pathogens that cause diseases such as malaria and amoebic dysentery. Additionally, studying protozoans can lead to advancements in biotechnology and environmental monitoring, given their sensitivity to ecological changes. Overall, knowledge of protozoans enhances our comprehension of biodiversity and ecosystem dynamics.
Yes, the are producers and at the 'bottom' of the food web.

No, not all protozoans are prokaryotic and autotrophic. Protozoans are eukaryotic organisms that can be autotrophic or heterotrophic. Autotrophic protozoans can photosynthesize like plants, while heterotrophic protozoans rely on organic matter for nutrition.
maybe a termite and the protozoans that live inside of it. termites cannot digest food without protozoans and protozoans do not get any food if the termites dont eat wood. so they would both die without the other. This is pretty much the same example as sheep with the algae that live in its digestive system that digest grass
In protozoans, the structure that enables them to take in food is called the cytostome, or "cell mouth." This specialized structure allows the organism to engulf food particles through a process known as phagocytosis. In some protozoans, cilia or flagella may help create water currents to direct food toward the cytostome. Once the food is ingested, it is enclosed in a food vacuole for digestion.
No Protozoans do not have skeleton. They are unicellular organisms.
