What is the difference between a detritivore and a decomposer?
(1 point)
While detritivores consume both plants and animals, decomposers only consume dead animals.
While detritivores feed on dead organic matter, decomposers actually break down dead or decaying organisms.
While detritivores consume animals, decomposers only consume plants.
While detritivores are heterotrophic, decomposers are autotrophic
While detritivores feed on dead organic matter, decomposers actually break down dead or decaying organisms.
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 chains focus on energy transfers, but food webs do not.
Food webs do not show connections between animals like food chains.
Food webs are more complex than simple food chains.
Food webs are more complex than simple food chains.
Taj incorrectly states that autotrophs are also known as consumers that need to feed on other organisms, including plants and animals, to gain energy. Which of the following best describes consumers that feed on other organisms such as plants and animals for energy? (1 point)
trophic levels herbivores carnivores heterotrophs
heterotrophs
Which of the following is the first trophic level in every ecosystem? (1 point)
autotroph
tertiary consumer primary consumer heterotroph
autotroph
What is the relationship between matter and energy in an ecosystem? (1 point)
Matter and energy are cycled through the ecosystem.
Matter and energy show the feeding relationships in an ecosystem.
There is no relationship between matter and energy in an ecosystem.
Matter and energy can only be modeled through food webs.
