Question
drag each label to the correct location on the diagram. each label can be used more than once, but not all labels will be used.
the diagram shows some of the steps in the flow of energy through an ecosystem. the arrows represent the transfer of energy. label each arrow
with the type of energy being transferred.
thermal
radiant
nuclear
chemical
electrical
- Sun to Plants: The sun produces energy via nuclear fusion, and the energy reaching plants is radiant (light) energy. So the arrow from sun to plants is labeled "nuclear" (source of sun's energy) and "radiant" (energy reaching plants). Wait, no, the sun's energy production is nuclear, and the energy transferred to plants is radiant (electromagnetic radiation, light). Then plants convert radiant energy to chemical energy via photosynthesis.
- Plants to Rodent: Plants store energy as chemical energy, so when a rodent eats plants, it's chemical energy transfer.
- Rodent to Owl: When an owl eats a rodent, the energy transferred is chemical (from the rodent's stored energy).
- Rodent to Wolf: Similarly, wolf eating rodent is chemical energy transfer.
- Owl to Surroundings: When organisms respire or decompose, energy is released as thermal energy (heat) to the surroundings.
- Wolf to Surroundings: Same as owl, thermal energy.
- Wolf to Decomposers: When the wolf dies, decomposers break down its organic matter, which contains chemical energy.
- Rodent to Decomposers: When the rodent dies, decomposers get chemical energy from its remains.
Let's map each arrow:
- Sun → Plants: The sun's energy is produced by nuclear fusion (nuclear), and the energy reaching plants is radiant (light) energy. Wait, the labels are thermal, radiant, nuclear, chemical, electrical. So sun's energy source is nuclear, and the energy transferred to plants is radiant (since it's light). But maybe the arrow from sun to plants: first, the sun's energy is nuclear (its internal process), then the energy going to plants is radiant. But maybe the diagram has one arrow from sun to plants. Wait, the diagram shows an arrow from sun to plants. So the sun's energy is nuclear (how it's produced), and the energy reaching plants is radiant. But the labels are to be dragged. Let's list the arrows:
- Sun → Plants: radiant (because the sun emits radiant energy (light) that plants use for photosynthesis; the sun's energy is generated by nuclear, but maybe the arrow from sun to plants is radiant. Wait, no—nuclear is the sun's energy source, but the energy transferred to plants is radiant. But the labels are given as thermal, radiant, nuclear, chemical, electrical. Let's think again:
- Sun to Plants: The energy from the sun to plants is radiant (light) energy. The sun produces energy via nuclear fusion (nuclear), but the energy reaching plants is radiant. So maybe the arrow from sun to plants is labeled "radiant" (the energy type reaching plants) and the sun's energy source is nuclear, but maybe the diagram has the sun's arrow as nuclear (the process) and radiant (the energy form to plants). Wait, maybe the first arrow (sun to plants) is "nuclear" (sun's energy production) and "radiant" (energy to plants). But the labels are separate. Let's check the energy flow:
- Sun (nuclear energy in its core) emits radiant energy (light) to plants.
- Plants convert radiant energy to chemical energy (photosynthesis), so Plants → Rodent: chemical.
- Rodent → Owl: chemical (rodent's chemical energy to owl).
- Rodent → Wolf: chemical.
- Owl → Surroundings: thermal (heat loss).
- Wolf → Surroundings: thermal.
- Wolf → Decomposers: chemical (wolf's organic matter has chemical energy).
- Rodent → Decomposers: chemical.
- Also, when organisms respire, they release thermal energy, but maybe the arrows to surroundings are thermal.
Let's assign each arrow:
- Sun → Plants: radiant (the light energy from sun to plants)
- Plants → Rodent: chemical (plants' stored chemical energy)
- Rode…

(Note: The sun’s energy is produced by nuclear fusion, so if the diagram includes the sun’s internal energy source, it could also have “nuclear” for the sun, but the energy reaching plants is radiant. Based on typical ecosystem energy flow diagrams, the above labels are standard for the given energy types.)
