Question

question 44 (1 point)
what type of organisms get their energy by eating other organisms? (select all that apply)

a decomposers
b herbivores (primary consumers)
c plants (producers)
d carnivores (secondary - quaternary consumers)

question 45 (1 point)
which claim(s) is supported by information in the diagram? select all that apply.

a the highest trophic level receives the least amount of energy in an ecosystem.
b 10 percent of the energy at a trophic level is transferred to the next trophic level
c 90 percent of the energy at a trophic level is transferred to the next trophic level.
d most of the energy lost to the environment is released as heat.

Explanation:

Question 44

• Decomposers break down dead organisms, not eat live ones for energy.
• Herbivores eat plants (producers) to get energy.
• Plants (producers) make their own energy via photosynthesis, not by eating others.
• Carnivores eat other organisms (herbivores or other carnivores) for energy.

• In a trophic level pyramid, energy decreases as trophic level increases, so the highest level gets the least energy (supports a).
• The 10% energy transfer rule states ~10% of energy at a trophic level moves to the next (supports b).
• 90% is lost (not transferred), so c is wrong.
• Energy lost is often as heat, but without the diagram, if the diagram shows energy flow with heat loss, d is supported. Assuming standard energy flow concepts, a, b, d are supported (if diagram aligns with 10% rule, energy decrease with trophic level, and heat loss).

Answer:

b. Herbivores (primary consumers), d. Carnivores (secondary - quaternary consumers)
