The Sun provides energy for the plants (producers) to grow. Herbivores (primary consumers) then eat the producers for energy. Any animals that eat the herbivores are considered secondary consumers. As this cycle continues, energy is lost to the environment as heat.

Answer:
Coevolution
Explanation:
Ehrlich and Raven observed butterfly species and their host plants. Plant species had adopted a series of defence mechanisms against butterflies. In response the butterflies also evolved new traits to avoid these defence mechanisms.
In this way both butterflies and plants influenced each other's traits and they co evolved. The coevolution can lead to accumulation of lot of different characteristics which can lead to formation of new species and species diversification. Formation of new species will be observed both in plants and butterflies.
