Answer:
They can perform photosynthesis.
Explanation:
Autotrophs are organisms that can produce their own food, and heterotrophs are organisms that feed on other organisms. This means that the ameba and paramecium can eat only other microorganisms.
The euglena is not limited to this. Hypothetically speaking, if there were no other microorganisms around it (which is unlikely), the euglena would not die as long as it is exposed to sunlight. Thanks to chloroplasts, organelles that contain chlorophyll, it can perform photosynthesis - a process in which, with the help of sunlight, carbon dioxide, minerals, and water are used to synthesize food.
Refined grain products like bread, flour tortillas, white rice, cornmeal, crackers etc are enriched with riboflavin, niacin, iron and thiamin.
Enriched grains is finely ground endosperm of the kernel. Enriched grain products are good as a source of iron and four types of vitamin B which includes niacin, thiamin, folic acid and riboflavin and also contains some complex carbohydrates.
Wheat and rice are a staple diet in many regions of the world but excessive polishing and refining the cereals removes the essential nutrients or vitamins which have their own important physiological roles.
It should be an explanation on what you wanna learn about in the experiment, it should be based on prior knowledge, it is also different from a prediction
The supporting structure of the cell that is also involved in movement is most likely the cytoskeleton.
A nucleus controls the movement of the cell, if that helps.
