5. Material Cycling in Aquatic Ecosystems
- Linking Climate Change and Fisheries |
| 5-1. Material cycling |
| All the biological processes consist of energy conversion, energy transfer and cycling of materials. For instance, primary production is a process to convert carbon dioxide into organic materials. Further food webs are viewed as multiple processes that transfer energy through prey-predator relationship networks. If the appropriate energy in each step is known, the biological processes can be understood and analyzed based on chemical theories. This approach enables us to understand how biomass, diversity and interactions among living organisms in aquatic environments are controlled. This approach is also important when clarifying the key step in the biological system and predicting the future status of marine resources. This sub-session, will describe and discuss various aspects of material cycling in the sea will be described and discussed. |
