Question

Which relationship is an example of commensalism? A) Hyenas and lions fight over the same antelope kill. B) A tapeworm lives in the intestine of a dog, obtaining food for itself, while slowly harming the dog. C) Remora fish stick to large sharks, receiving a free ride and scraps of food the shark does not eat. The shark is neither helped nor harmed. D) A diamondback rattlesnake and a gopher turtle share a burrow. The turtle digs the hole, and the snake provides protection from predators for the turtle.

Answer 1

The answer is C because in a commensalism relationship, one benefits and the other isn't necessarily benefited but it's not harmed. So Remora fish are benefited with the sharks scraps for food but the shark isn't harmed.

Answer 2

Answer:

The correct answer is option C) "Remora fish stick to large sharks, receiving a free ride and scraps of food the shark does not eat. The shark is neither helped nor harmed".

Explanation:

Commensalism is defined as a type of interspecies relationship at which one individual gets benefited and the other is neither benefited or harmed. An example of commensalism is the one between remora fish and large sharks. In this case, remora fish gets attached to the large sharks by an organ that acts suction cup. The remora fish gets benefited by receiving transportation, a food source and protection from predators, while the large sharks are neither helped nor harmed.
