Deep ocean anglerfish have special organs that utilize chemical energy to produce light that the fish uses to capture prey. The
DerKrebs [107]

<u>Answer:</u>

<em>Deep sea anglerfish makes use of bioluminescence to attract prey as well as potential partners and this doesn’t violate the law of conservation of energy. </em>

<u>Explanation:</u>

<em>Deep sea anglerfish</em> lives at very big depths under the sea and thus there is hardly any light available at these depths. The <em>anglerfish depends on bacteria</em> for luminescence since it cannot produce light on its own. Thus it maintains a <em>symbiotic relationship with the photobacteria. </em>

There is no violation of energy conservation law here. The light energy is not produced from nothingness but from the bacteria. There is no <em>creation of energy or destruction of energy in this case. </em>
