Question

the word \hydroponic\ means \working water.\ hydroponics is growing plants in water that has nutrients added to it, called a nutrient solution. the roots of the plant draw up nutrients from this solution instead of from the soil. hydroponics is a very efficient way to grow food, because an acre of nutrient solution can grow 50 times more lettuce than an acre of land. most vertical farms use hydroponics.
aeroponics was developed by the national aeronautical and space administration (nasa). nasa defines aeroponics as \growing plants in an air/mist environment with no soil and very little water. aeroponics is the most efficient way to grow plants in a vertical farm, because it uses up to 90% less water, and the plants uptake more nutrients.
aquaponics combines growing plants and fish together in the same ecosystem. the fish live in indoor ponds, and their nutrient - rich waste acts as a food source for the plants also living in the vertical system. in this way, the plants filter and purify the wastewater, which is continuously recycled back through the system.
community supported agriculture
community supported agriculture (csa) is a system in which customers can buy local food directly from the farmer that produces it. csas typically operate as subscription services. the customer purchases a \share\ that entitles them to a regular allotment of vegetables for the duration of the growing season.
customers pick up their shares at designated times and locations.

a. hydroponics
b. aeronautics
c. aeroponics
d. aquaponics

1. a system in which customers buy local food directly from the farmer is called:

Explanation:

Question 13:

The text says "The word 'hydroponic' means 'working water'". So we check the options: a is Hydroponics, which matches the definition.

The text states "Aquaponics combines growing plants and fish together in the same ecosystem". So the word is Aquaponics, which is option d.

The text describes "Community Supported Agriculture (CSA) is a system in which customers can buy local food directly from the farmer". So the system is Community Supported Agriculture.

Answer:

a. Hydroponics
