African clawless otters (Aonyx capensis) typically feed on a combination of two food types, namely crabs and fish. Suppose that these two prey types are perfectly substitutable resources to otters. Draw and label a diagram, using isoclines, to illustrate such the situation described above. Include in your diagram representations that illustrate the position of isoclines (relative to one another) that illustrate resources levels that you would expect to lead to decrease
