- Draw a food chain for Puget Sound using these organisms and abiotic components. Some possible organisms to include in the food chain are: herring, marine bacteria, people, phytoplankton, pteropods, krill, oysters, Dungeness crab, salmon, Orcas.If the ecological footprint per person of a country or theworld is larger than its biological capacity per person toreplenish its renewable resources and absorb the resulting waste products and pollution, the country or theworld is said to have an ecological deficit. If the reverse istrue, the country or the world has an ecological credit orreserve. See Figure 1.11 for a map of the world’s ecologicaldebtor and creditor countries. Use the data to the right tocalculate the ecological deficit or credit for the countrieslisted. (As an example, this value has been calculated andfilled in for the world.)1. Which three countries have the largest ecologicaldeficits? For each of these countries, why do youthink it has a deficit?2.
