Question

Some people blamed the decrease of otter numbers on mink. give three reasons why this seemed possible. Explain your answers.

I could only think of one answer, which was about food competition-

please help!!

thanks

Answer 1

From what I've read, it's likely that mink didn't cause the decrease in otter numbers. However, aggressive mink behavior, taking over some of the otter's habitat, as well as food competition could make it seem possible.

It seems to be the other way around.

Since this is not my area of expertise, I searched Google under the key words "<I>mink otter</I>" to get these possible sources:
