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.

Examine the model and the relationships between the major players (i.e., predator, prey, producer). The structure's most important role is played by these major players. It's also worth noting that nutrition has been included in the model. This is the abiotic component that has a direct or indirect impact on the interaction.
