A) What is the difference between a detritivore and a decomposer? (1 point)
While detritivores feed on dead organic matter, decomposers actually break down dead or
decaying organisms.
While detritivores consume both plants and animals, decomposers only consume dead animals.
While detritivores consume animals, decomposers only consume plants.
While detritivores are heterotrophic, decomposers are autotrophic

A) What is the main difference between food chains and food webs? (1 point)
Food chains focus on the internal energy cycles of animals, unlike food webs.
Food webs do not show connections between animals like food chains.
Food chains focus on energy transfers, but food webs do not.
Food webs are more complex than simple food chains
