      1 Explain how the competitive exclusion principle and the unified neutral theory vary in explaining species coexistence.

      2 How can we make use of physiological information such as photosynthetic pathway (e.g., C3 vs. C4) of component species in designing sustainable agroforestry systems?

      3 Although shading is commonly associated with competition for light, shading can be beneficial in agroforestry systems. Describe the beneficial or facilitative role of shading with the help of examples.

      4 What is meant by “safety‐net hypothesis” in an agroforestry context? Provide an example each from (a) alley cropping, (b) silvopasture, and (c) riparian buffer.

      5 Agroforestry systems seem to have fewer pest problems than their monoculture counterparts.
