Question

living lights
1 during the day, we get light from the sun. at night, we flip on an electric light switch or light a fire. but some bioluminescent organisms produce their own light. one familiar example of bioluminescence is the flashing light of fireflies, also known as lightning bugs. bioluminescence is light produced by chemicals inside living things.
2 many ocean predators use bioluminescence to find and catch their food. some do so by using light to attract prey. for example, an anglerfish has a long, thin growth on its head, with a tip that lights up. small fish swim toward the light, and the anglerfish grabs them with its sharp teeth. other
which is the best summary of the text?
bioluminescent creatures produce light inside their bodies. many sea animals are bioluminescent, and they use it to protect themselves, catch prey, and attract mates. people are bioluminescent, too. but people have not figured out how to use bioluminescence yet.
bioluminescent organisms produce light using chemicals inside their bodies. some sea animals produce their own bioluminescent light. they use this light to help them catch food, hide from predators, and find mates. people have also found ways to use the bioluminescence these organisms produce.
bioluminescence is light produced by chemicals inside some organisms. ocean predators use bioluminescence to attract prey or to locate their prey. other sea creatures protect themselves with bioluminescence by using it to hide from, scare away, or escape from predators.

Explanation:

To determine the best summary, we analyze each option against the text:

1. First option: The text does not mention people being bioluminescent or people trying to use bioluminescence. Eliminate this.
2. Second option: The text does not discuss people using bioluminescence or sea creatures using it to find mates/hide from predators. Eliminate this.
3. Third option: The text defines bioluminescence (light from chemicals in organisms) and explains ocean predators use it to catch prey (e.g., anglerfish attracting prey). It also aligns with the idea of other sea creatures using it for protection (implied by the broader context of bioluminescence in marine life, even if the text’s examples focus on predators, the option’s mention of protection is consistent with typical bioluminescence uses and the text’s scope).

Answer:

Bioluminescence is light produced by chemicals inside some organisms. Ocean predators use bioluminescence to attract prey or to locate their prey. Other sea creatures protect themselves with bioluminescence by using it to hide from, scare away, or escape from predators.
