Bioluminescence

The production of light by living organisms is

• bioluminescence

• evolution

• adaptation

• chemistry

Nearly all midwater bioluminescence is

• red

• rainbow

• yellow-orange

• blue-green

Many small light sources on the underside of an organism hides the silhouette when viewed from above is known as

• communication

• counterillumination

• evolution

• adaptation

Uses of bioluminescence include

• attract or search for prey

• avoid predators

• attract mates

• decoys

Biolumines can be vomited.

• True

• False

A chemical reaction where light is produced is known as

• chemistry

• fluorescence

• phosphorescence

• chemiluminescence

Bioluminescence occurs in _______ of organisms in the pelagic zone.

• 5-10%

• 50%

• 80-90%

• 75%

A fraction of light is absorbed and remitted as different color. Only visible in the presence of a stimulation light.

• siphonophores

• phosphorescence

• fluorescence

• chemiluminescence

Why would the Navy be interested in bioluminescence?

• to light up the night sky

• could be kept for pets

• they could reveal the enemy

• to fish at night

NGSS.MS-ETS1-3

Similar to fluorescence but light is emitted for a much longer time after the external light is removed

• substrates

• adaptation

• fluorescence

• phosphorescence
