Figure 50.3 Examples of questions in different subfields of ecology: 

Figure 50.3 Examples of questions in different subfields of ecology (a) Organismal ecology. How do humpback whales select their calving areas? (c) Community ecology. What factors influence the diversity of species that make up a particular forest? (d) Ecosystem ecology. What factors control photosynthetic productivity in a temperate grassland ecosystem? (e) Landscape ecology. To what extent do the trees lining the drainage channels in this landscape serve as corridors of dispersal for forest animals?
