The base of the pyramid is composed of species called autotrophs, the primary producers of the ecosystem. Animals have two systems of internal communication and regulation, the nervous system and the endocrine system. In addition to the importance of trophic cascades in determining ecosystem composition (see previous section), trophic network theory highlights the importance of key species in ensuring a .
