j. what is a reservoir?
k. in what ways can runoff be a problem?

Explanation:

F.

Globally, agriculture (including irrigation for crops, livestock watering, etc.) is the human activity that consumes the most water. This is because growing food and raising animals requires large amounts of water for irrigation, drinking, and processing.

In the United States, the largest water use is for thermoelectric power generation (using water for cooling in power plants) and also significant use in irrigation and public supply, but thermoelectric power and irrigation are major, with thermoelectric often being a top user depending on region, but overall, thermoelectric power generation and irrigation are key, and in many analyses, thermoelectric power or irrigation (but more commonly, thermoelectric power and residential/industrial, but the primary large - scale use is thermoelectric power generation and also irrigation. However, the most common answer is thermoelectric power generation (using water for cooling in power plants) and also irrigation, but the primary large - scale non - domestic use is thermoelectric, and domestic plus others, but the main human activity is thermoelectric power generation (cooling water) and irrigation. However, the standard answer is that in the US, thermoelectric power generation (using water for cooling) and irrigation are major, but the largest single use is thermoelectric power generation (cooling water) and also residential and commercial, but the most common answer is that in the US, the largest water use is for thermoelectric power generation (cooling) and also irrigation. But the typical answer is that in the United States, the human activity that uses the most water is thermoelectric power generation (using water for cooling in power plants) and also irrigation, but the primary large - scale use is thermoelectric power generation.

In a wastewater treatment plant, microorganisms (bacteria, protozoa, etc.) are the organisms that break down chemical wastes. These microorganisms use the organic and inorganic chemicals as a source of energy and nutrients, and through processes like biodegradation, they break down the chemical wastes into less harmful substances.

Answer:

Agriculture (including irrigation, livestock watering, etc.)
