The following sentences are taken from a draft of an essay about marine biology.
[1] This glowing display helps the squid attract prey and communicate with potential mates in the darkness.
[2] Bioluminescence is the production and emission of light by a living organism.
[3] For example, the firefly squid uses light-producing organs called photophores to illuminate the deep ocean.
The writer wants to organize the sentences in the paragraph so that it logically transitions from a general definition of bioluminescence, to a specific organism that uses it, and finally to the biological purpose of that light. What is the correct order of these sentences?
- 1Bioluminescence is the production and emission of light by a living organism.
- 2For example, the firefly squid uses light-producing organs called photophores to illuminate the deep ocean.
- 3This glowing display helps the squid attract prey and communicate with potential mates in the darkness.
Answer
The correct order of sentences is: 'Bioluminescence is the production and emission of light by a living organism,' followed by 'For example, the firefly squid uses light-producing organs called photophores to illuminate the deep ocean,' and concluding with 'This glowing display helps the squid attract prey and communicate with potential mates in the darkness.'
The correct order logically builds from the general definition of bioluminescence to the specific example of the firefly squid, and then to the practical function of the squid's photophores. This sequence fulfills the rhetorical goal of transitioning from general definition to specific example, to biological purpose.
