资源简介：
The "Wetlands" unit includes three activities that are designed to promote an understanding of the transfer of nutrients and energy through food chains and food webs. Students recognize the interdependence of all living things by this comparison. The activities illustrate the basic ecological components of a wetland ecosystem, their relationship via food chains, and finally the flow and loss of energy in a saltwater and freshwater marsh ecosystems.
