Euglena


Mushrooms


Paramecium

Question 22 (1 point)
Compare this fungus with the protist shown in the images below. How do they differ in the way they obtain nutrients?



Question 22 options:

Both organisms are autotrophs. The mushroom uses hyphae to get its nutrients and the amoeba uses the pseudopod instead.




Both organisms are consumers. The amoeba engulfs its food with it;s pseudopod, while the fungus absorbs food from the dead leaves using its hyphae.




The amoeba is a producer and obtains nutrients through photosynthesis; the fungus is a consumer and is decomposing leaf litter in the forest.
