Question 1

what is urban metabolism?

Answer 1

a model to facilitate the description and analysis of the flows of energy and material within the cities

Question 2

what do urban metabolism studies help us to understand?

Answer 2

they help us understand what happens to resources between the point of entryng the city and the exit in the cities waste

Question 3

what two types of metabolism are there?

Answer 3

linear metabolism and circulair metabolism

Question 4

what is linear metabolism?

Answer 4

fast majority of resources that enter the city leave it again as solid, liquid and air worn waste

Question 5

what is circulair metabolism?

Answer 5

re-use the waste as new resources, almost no waste and everything is being reused

Question 6

what is sustainable (development)?

Answer 6

fufilling the needs of the current generations, without compromising the need of further generations, while ensuring a balance between economic growth, environmental care and social well-being

Question 7

sociometabolism=

Answer 7

set of flows of materials and energy that occur between nature and society

Question 8

ecosystem=

Answer 8

community of living organisms in conjuction with the non-living components of their environment, interacting as a system

Question 9

biotic=

Answer 9

living

Question 10
