Dennis Campbell,David S. Tenzerons also provide a marvelously efficient system for communication and they enable various levels of prediction. Unfortunately, systematics and biological diversity are generally misunderstood because the general populace holds a simplistic view of the complexity and size of the world’s biota.

Ecology of agroecosystems in relation to natural ecosystemsosystems are in existence. The transformation of these ecosystems into agroecosystems largely depends on cultural background, level of technology, and political decisions. In consequence, a wide variation of agroecosystem development, ranging from the simplest to the most advanced, exists today.
