Answer:
An artesian aquifer is a confined aquifer containing groundwater under positive pressure. An artesian aquifer has trapped water, surrounded by layers of impermeable rock or clay which apply positive pressure to the water contained within the aquifer.
A force that makes a flow of water strong or weak high/low water pressure.
The soil or rock located below the top of the groundwater table. By definition, the zone of saturation is saturated with water. Also see water table. Where raw wastewater is exfiltrating from a sewer pipe, the area of soil that is moistened around the leak point is often called the zone of saturation.
Porosity or void fraction is a measure of the void spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and 100%. Strictly speaking, some tests measure the "accessible void", the total amount of void space accessible from the surface.

Answer:
c) Tertiary consumers always have greater body mass than primary and secondary consumers in a given system
Explanation:
This statement has two flaws. One of them is that the tertiary consumers usually tend to have smaller body mass than the primary and secondary consumers, so it is a false statement. The other one is that it doesn't have any connection with the numbers of the tertiary consumers compared to the primary and secondary consumers. There are several reasons as to why the tertiary consumers tend to be much more rare than the primary and secondary consumers. The lesser amount of food energy available to them and the need of very large ranges to satisfy the food energy demand of their bodies being the two crucial ones. Through the trophic levels, the energy transferred fro one to another trophic level is around 10%, so the tertiary consumers get very little from the initial energy. Also, because they need much more food in order to satisfy their energy demands, they have to have large ranges, with abundance of prey animals, so that they can survive, which is another reason as to why they are much fewer in number than the primary and secondary consumers.
