There are a wide range of potential costs and benefits of living in a group. Sometimes these costs and benefits can create tradeoffs with respect to optimal group size. The following graphs show two such factors – risk of disease (in red) and risk of predation (in black). Researchers can use these relationships to predict optimal group size (yellow star). Which of the following graphs is most consistent with what you would expect for these costs and benefits of group living?
