Q1.24. Kodric-Brown and Brown wanted to explore how reducing territory quality would affect foraging behavior. They created low-density territories by removing half the flowers, and they compared them to high-density, unmanipulated territories. Which of the four graphs below best illustrates how reducing flower density will affect the cost (C) benefit (B) curve of the low-density territory? (Subscripts indicate whether the curve represents a territory with a high-density (H) or low-density (L) of flowers.) си B Benefits/Costs Benefits/Costs Territory size (m)...
