Answer:
D. heterotrophic by ingestion, pseudopods
Explanation:
Protists are generally classified as all eukaryotic organisms that are not plants, animals or fungi. Example is amoeba, paramecium etc.They may be unicellular or multi cellular in nature.Most exist in colonies.
Their mode of nutrition can be photosynthetic or hetrotrophic. Hetrotrophic protists can be divided into phagotrophs and osmotrops/saprotrophs. The phagotrophs makes use of the cell body to engulf the food materials as in amoeba ,carry out extracellular digestion before swallowing it.
Osmotrops absorbed dissolved food from surrounding liquid environments directly. (Some photosynthetic protists can also be heterotrophic.
Amoeboid movement is the mode of locomotion of protists and some other eukaryotes. It involved the protrusion of cytoplasm, which exert pressure on the cell membrane to form pseudopodia and the posterioly evolved <u>Uropods. </u>

<u>Sol-gel theory has been proposed to expalin this movements, The ectopalsm of amoeba is gelly-like , while the endiplams is less viscpus and said to be sol. The interchange of the cytoplasmic fluis between the endo-and ecto plasm gives the SOL-GEL propulsion of the protopalms for the amoebic moveemnts .</u>

<u>The false feet(psuedopodium) drags the amoeba along in the direction of the flow of the cytoplasm.</u>
Therefore option D is the right option
Answer:
218.75 grams of protein.
Explanation:
If 2500 protein is consumed and its 35% energy is provided by protein then:
2500÷35×100 =875 kcal would be provided by protein.
As one gram of protein provide 4 kcal of energy:
875÷4 = 218.75 grams of potein would be consumed.
<em>Remeber the calories and kcal for food is same.</em>
