Answer:
According to bottom-up and top-down control models of community organization, which of the following expressions would imply that an increase in the size of a carnivore (C) population would negatively impact on its prey (P) population, but not vice versa? D) P ← C
Explanation:
A community is defined by all the organisms living in the same area. In nature, theses communities are organized in a bottom-up or a top-down model.
