（1）introduction

Human being are confronted with the five crisis such as , food, , , environment.

Divided by the organization levels, the ecology include molecular ecology, autoecology, ecology, ecology, ecology, ecology, global ecology. Divided by the habitat, ecology include terrestrial ecology, ecology, estuary ecology, ecology, etc.

Divided by the organisms, ecology include ecology, ecology, and microorganism ecology.

Classic ecology include autoecology, , , , and ecosystem ecology.

（2）autoecology
