PLEASE HELP!!

A certain grey squirrel population has lived in Tomlinson Run State Park, West Virginia, for more than 20 years. A red squirrel population was introduced into the park two years ago and has become a large competitor for food and other resources for the grey squirrel. There has also been a decline in the park’s grey squirrel population during the last two years. Which of the following best explains this scenario?

A) commensalism

B) Gause’s law

C) mutualism

D) Boyle’s law

Respuesta :

Based on the scenario above, the presence of both squirrels clearly shows commensalism. Commensalism is one of the symbiotic relationships wherein one organism benefits from the other without harming it. In this case, it is the red squirrel that has mostly benefited from the grey squirrel but this also left the grey squirrel unharmed. Answer is option A.
