The kingdom fungi contains many simple organisms like the one you see above. compare this fungus with the protist seen here, an algae called volvox. how do they differ in the way they obtain nutrients? a) both organisms are producers. volvox uses photosynthesis to get nutrients. the fungus uses chemosynthesis instead. b) both organisms are consumers. the volvox engulfs its food while the fungus absorbs food from the dead leaves using its hyphae. c) volvox is a producer and obtains nutrients through photosynthesis; the fungus is a consumer and is decomposing leaf litter in the forest. d) volvox gets nutrients through the process of photosynthesis. the fungus catches small insects under its cap and consumes the insects as food.
