- http://www.fao.org/nr/water/aquastat/data/query/index.html?lang=en. Step 1. Choose five nations (including the United States) from the enormous database by clicking the corresponding boxes. For "select variables", choose these three: 1. Under "Water Resources" choose "Total Renewable Water Resources" and within that choose only "Total Renewable Water Resources per Capita. 2. Choose "Water Use" and then "Pressure on Water Resources" . Within that subset choose only"SDG 6.4.2 Water Stress". "SDG" means the Sustainable Development Goal. This value is the percentage of total available water that is used by a nation. 3. Under "Water Use" choose "Water Withdrawal by Sector", and within that choose only "Total Water Withdrawal per Capita". Nation Resources per Capita Withdrawal per Capita % Water Stress: withdrawal vs. resources) Step 2. Based…Which of the following statements about biotic potential is TRUE? Biotic potential of an organism is determined by how they interact with the environment. Increase in food supply increases the biotic potential of an organism. If an organism has higher rate of reproduction, it has higher biotic potential. Small organisms have low biotic potential because of their size.Pollution is caused mainly through anthropogenic activities.
